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

help: make listexts less confusing for deprecated exts Return an empty array instead of a heading and no items
