webcommands: get correct parents when comparing a removed file (issue4962) When comparing a file that was removed at the current revision, parents used to show grandparents instead, due to how fctx was "shifted" from the current revision to its p1. Let's not do that. The fix is pretty much copied from webcommands.filediff().

repair: use bookmarks.recordchange instead of bookmarks.write Before this patch we were using the deprecated bookmarks.write api. This patch replaces the call to bookmarks.write by a call to bookmarks.recordchange. We move the bookmark code above the code removing the undo file because with bookmarks.recordchange we have to create a transaction that would create an undo file.

commit: add amend mode for commit -i When I moved crecord into core, I didn't include the toggleAmend function (to switch from commit to amend mode). I did it because it would have made it more difficult to use record and crecord interchangably. This patch reintroduces the amend mode for commit -i as well as two tests to verify the behavior of the function.

commit: add a way to return more information from the chunkselector Before this patch, the chunkselector for record or crecord was used to return the list of hunks that were selected by the user. The goal of this series is to reintroduce the toggle amend feature for crecord. To do so, we need to be able to return more than just the selected hunks from the chunkselector but also the information: is amend mode toggled. This patch adds a new return value for chunkselectors that will be used to implement the toggle amend feature in crecord.

histedit: edit with custom filename For instance, Emacs allows to open file with special features enabled (AKA mode) based on the path/name of the file [1]. For such cases, use 'hg-histedit-XXX.txt' as filename pattern. [1] https://www.gnu.org/software/emacs/manual/html_node/emacs/Choosing-Modes.html

ui: allow open editor with custom filename By default, editor will use temp file named after hard-coded pattern 'hg-editor-XXX.txt' which makes it impossible for extensions to use another filename if desired. Now the middle part of the pattern ('editor') can be changed by setting extra['prefix'].

help: make help deprecated mention the extension before this, you got an empty list of extensions, which was unhelpful
