    // NOTE(matt): Path types:
    //                  WT_ASSET: File, but we seem to strip the file component from the path, leaving the parent directory
    //                  WT_CONFIG: Directory of -c config, then File of existing config files
    //                  WT_HMML: Directory
    //
    //                  So do we need to watch Files and Directories differently?
    //
    //              We could surely detect the type of Path we've been passed, whether DIR or FILE
    //
    //              Rationale:
    //                  WT_HMML:    We must watch the directory, so that we can actually pick up new .hmml files
    //                              HMML filenames are supposed to end .hmml, so we may use that to make sure we pick out the
    //                              watch handle
    //                              And we point to the Project so that we may switch to the correct CurrentProject
    //
    //                              For HMMLDir that don't exist, they may come into existence after the initial Sync.
    //                              How can we handle this? Must we watch the nearest existing ancestor directory, and keep
    //                              progressively swapping that out until we're watching the HMMLDir itself?
    //
    //                              Do we augment watch_handle with "NearestAncestorPath", in addition to TargetPath?
    //                              So if the TargetPath doesn't exist, we instead watch the NearestAncestorPath. The all watch
    //                              handles have a valid WatchDescriptor (i.e. not -1).
    //
    //                  WT_CONFIG:  We must watch the -c directory, to enable us to handle the absence of a config
    //                              But thereafter, we may (and probably should) watch the files directly, as we are doing
    //                              The reason to watch at all is to enable live-reloading
    //                  WT_ASSET:   We have a finite set of assets, right? So shouldn't that mean that we could just watch the
    //                              files directly?
    //
    //                              We have BuiltinAssets, which we push onto the Assets whether or not the file exists, but we
    //                              only push their watch handle if the file does exist. Maybe any time we create an asset file,
    //                              e.g. cinera_topics.css, or we see an asset file referred to in a template, we try pushing on
    //                              its watch handle.
    //
    //                              Q: Why watch at all?
    //                              A: So that we can rehash the file and snipe its new checksum into the html files
    //                              So wouldn't it be worth pointing to the Asset directly, so that we have immediate access to
    //                              this data?
    //
    //                  Permitting multiple "types" at the same path?
    //
    //                  This could only possibly happen for directories, which excludes WT_ASSET.
    //                  WT_HMML
    //                      We determine it to be a WT_HMML if the filepath ends .hmml
    //                  WT_CONFIG
    //                      The only WT_CONFIG directory is the parent of the -c, whose path we always know
    //
    //
    //              Side issue: Why bother storing the whole path, when the Event->name only contains the BaseFilename?
    //                          Is it so we can distinguish between paths when pushing / getting watch handles?
    //
    //                          I reckon we store the Target and the Watched paths, both of which must surely be the full thing
    //
    //              Symlinks:   What do we watch? The symlink, or the path to which the symlink points?
    //
    //              Okay, I reckon what we do is the following:
    //
    //                  watch_handle
    //                  {
    //                      char *TargetDirectory
    //                      char *WatchedDirectory
    //                      int FileCount
    //                      char **Files
    //                  }
    //
    //                  The Target and Files remain the same always
    //                  The WatchedDirectory may change according to which directories exist
    //
    //                  Watch the target directory
    //                  For each watch_handle, list out the specific files that we're watching
    //
    //                  We only need to write anything into the book once
    //
    //                  WrittenPath:
    //                      /home/matt/tmp/file
    //                      Filename: file
    //                      TargetPath: /home/matt/tmp
    //
    //                  If we write the WrittenPath, then realise that the TargetPath is already in there, we'd inadvertently
    //                  erase the whole WrittenPath
    //
    //                  If we write the Filename then the TargetPath, then realise the TargetPath is already there, we'd erase
    //                  the TargetPath just fine. But then if we later realise we have the Filename too, we have no way to erase
    //                  that. While suggests that we should straight up make the memory_book Current be part of a linked list,
    //                  so we could erase multiple things if needed.
    //
    //                  But, write the Filename, then the TargetPath:
    //                      TargetPath doesn't already exist
    //                      Filename, couldn't already exist
    //
    //                      TargetPath does exist, so may be erased
    //                      Filename
    //                          does exist, so may be erase
    //                          doesn't exist, so must remain
    //
    //                  Seems like we really want to "resolve" the whole path somewhere temporary (on the stack), then:
    //                  string Filename = GetFinalComponent(Wrap0(Temp));
