     $stash is an internal-use-only object for managing "stashed"
     local edits, to help avoid that users accidentally lose content
     by switching tabs or following links or some such. The basic
     theory of operation is...

     All "stashed" state is stored using fossil.storage.

     - When the current file content is modified by the user, the
       current stathe of the current P.finfo and its the content
       is stashed. For the built-in editor widget, "changes" is
       notified via a 'change' event.  For a client-side custom
       widget, the client needs to call P.stashContentChange() when
       their widget triggers the equivalent of a 'change' event.

     - For certain non-content updates (as of this writing, only the
       is-executable checkbox), only the P.finfo stash entry is
       updated, not the content (unless the content has not yet been
       stashed, in which case it is also stashed so that the stash
       always has matching pairs of finfo/content).

     - When saving, the stashed entry for the previous version is removed
       from the stash.

     - When "loading", we use any stashed state for the given
       checkin/file combination. When forcing a re-load of content,
       any stashed entry for that combination is removed from the
       stash.

     - Every time P.stashContentChange() updates the stash, it is
       pruned to $stash.prune.defaultMaxCount most-recently-updated
       entries.

     - This API often refers to "finfo objects." Those are objects
       with a minimum of {checkin,filename} properties (which must be
       valid), and a combination of those two properties is used as
       basis for the stash keys for any given checkin/filename
       combination.

     The structure of the stash is a bit convoluted for efficiency's
     sake: we store a map of file info (finfo) objects separately from
     those files' contents because otherwise we would be required to
     JSONize/de-JSONize the file content when stashing/restoring it,
     and that would be horribly inefficient (meaning "battery-consuming"
     on mobile devices).

       the content. The assumption/hope is that the browser can store

`/fileedit` will, if possible, store them in `window.fileStorage`
or `window.sessionStorage`, if available, but...

- Which storage is used is unspecified and may differ across
  environments.
- If neither of those is available, the storage is transient and
  will not survive a page reload.
- It stores only the most recent checkin/file combinations which have
  been modified (exactly how many may differ - the number will be
  noted somewhere in the UI). Note that changing the "executable bit"
  is counted as a modification, but the checkin comment is not stored
  separately for each file. If the limit is exceeded, it silently
  discards the oldest edits.

Exactly how long `fileStorage` will survive, and how much it or
`sessionStorage` can hold, is environment-dependent. `sessionStorage`
will survive until the current browser tab is closed, but it survives
across reloads of the same tab.

If `/filepage` determines that no peristent storage is available a
