hgk: update backgroud colour when Ttk is available Ttk doesn't automatically set up Tk colour palette. Because of that, Ttk controls look differently when used together with old Tk controls. When we use Ttk controls, we first query if we have any setting for the client background, and if we do, we update Tk palette as well.

hgk: fix pop-up windows Create pop-up windows properly so they go to the floating layer in tiling window managers.

hgk: don't use fixed format for dates Don't pass -format with a date format string, use default instead so users can use their own preferences.

hgk: reformat changsets fields Rename Author to User. Rename Revision to Changeset. Put Date on its own line.

hgk: drop committer field from the UI Remove Committer field, it doesn't make sense in Hg.

test-completion: test completion of tags

debugpathcomplete: satisfy the code checker

tests: test debugpathcomplete and debuglabelcomplete

tests: rename test-debugcomplete.t to test-completion.t

pathcomplete: complete directories more conservatively Suppose we want to perform a single-level completion (i.e. without --full) of "fi" in a repo containing "fee", "fie/dead", "fie/live", and "foe". If we give back "fie/" as the only answer, the shell will consider the completion to be unambiguous, and will append a space after the completion. We can't complete "fie/live" or "fie/dead" without first backspacing over that space. We used to thus create two fake names, "fie/a" and "fie/b", to force the shell to consider the completion to be ambiguous. It would then stop at "fie/" without appending a space, allowing us to hit tab again to complete "fie/live" or "fie/dead". The change here arises from realising that we only need to force the shell to consider a completion as ambiguous if we have exactly one directory and zero files as possible completions. This prevents spurious names from showing up as possible completions when they don't need to be invented in the first place.
