narrow: use narrow_widen wireproto command to widen in case of ellipses Few releases ago, we introduce narrow_widen wireproto command to be used to widen narrow repositories. Before this patch, that was used in non-ellipses cases only. In ellipses cases, we still do exchange.pull() which can pull more data than required. After this patch, the client will first check whether server supports doing ellipses widening using wireproto command or not by checking server's wireproto capability. If the server is upto date and support latest ellipses capability, we call the wireproto command. Otherwise we fallback to exchange.pull() like before. The compat code make sure that things works even if one of the client or server is old. The initial version of this patch does not had this compat code. It's added to help Google release things smoothly internally. I plan to drop the compat code before the upcoming major release. Due to change to wireproto command, the code looks a bit dirty, next patches will clean that up. Differential Revision: https://phab.mercurial-scm.org/D6436

== New Features ==

 * New config `commands.commit.post-status` shows status after successful
 commit.


== New Experimental Features ==

 * New config `experimental.log.topo` makes `hg log -G` use
   topological sorting. This is especially useful for aliases since it
   lets the alias accept an `-r` option while still using topological
   sorting with or without the `-r` (unlike if you use the `sort(...,
   topo)` revset).


== Bug Fixes  ==

 * issue4292: "hg log and {files} {file_adds} {file_mods} {file_dels}
   in template show wrong files on merged revision". See details in
   "Backwards Compatibility Changes".


== Backwards Compatibility Changes ==

 * Removed (experimental) support for log graph lines mixing
   parent/grandparent styles. Setting
   e.g. `experimental.graphstyle.parent = !` and
   `experimental.graphstyle.grandparent = 3.` would use `!` for the
   first three lines of the graph and then `.`. This is no longer
   supported.

 * If `ui.origbackuppath` had been (incorrectly) configured to point
   to a file, we will now replace that file by a directory and put
   backups in that directory. This is similar to how we would
   previously replace files *in* the configured directory by
   subdirectories.

* Template keyword `{file_mods}`, `{file_adds}`, and `{file_dels}`
   have changed behavior on merge commits. They used to be relative to
   the first parent, but they now consider both parents. `{file_adds}`
   shows files that exists in the commit but did not exist in either
   parent. `{file_dels}` shows files that do not exist in the commit
   but existed in either parent. `{file_mods}` show the remaining
   files from `{files}` that were not in the other two
   sets.


== Internal API Changes ==

 * Matchers are no longer iterable. Use `match.files()` instead.

 * `match.visitdir()` and `match.visitchildrenset()` now expect the
   empty string instead of '.' to indicate the root directory.

 * `util.dirs()` and `util.finddirs()` now include an entry for the
   root directory (empty string).
