histedit: use the editor gotten by "getcommiteditor()" for "message" Before this patch, "hg histedit" for "message" uses "ui.edit()" for commit message editing. It shows original commit message, but not detail about the target revision: status of each modified/added/removed files, for example. This patch uses the editor gotten by "getcommiteditor()" instead of "ui.edit()" for "message" In "test-histedit-edit.t", this patch omits "fixbundle" invocation, because it prevents from confirming the "HG: added f" line in commit message by filtering " added " lines. Omiting "fixbundle" invocation causes that the exit code of "hg histedit" appears as one of command line: in this case, "hg histedit" is aborted by (expected) exception raising.

fetch: use "getcommiteditor()" instead of explicit editor choice This patch also enhances "test-fetch.t", because "hg fetch" hasn't been explicitly tested around editor invocation and '--edit' option.

cmdutil: introduce "getcommiteditor()" to simplify code paths to choose editor "getcommiteditor()" can simplify code paths to choose commit editor according to '--edit' option as below: before: editor = cmdutil.commiteditor # or editor = None/False if opts.get('edit'): editor = cmdutil.commitforceeditor after: editor = cmdutil.getcommiteditor(**opts) "getcommiteditor()" accepts option arguments not in "opts" style but in "**opts" style, because some code paths want to invoke it with just explicit "edit=True" argument (building dictionary is redundant).

update: when deactivating a bookmark, print a message This helps prevent user confusion when innocent-seeming commands like 'hg update -C .' are run.

doc: improves merge-tools example with an overwrite of existing config We highlight the fact that a user hgrc can overwrite the system wide preconfiguration. As other benefit we show priority value other than 1 and shows vimdiff configuration is usually directly available. This is valuable as vimdiff is (surprisingly) a common request from user.

help: add additional information in the merge-tools section of config help The merge tool configuration in general has always been a confusing topic for user. We add mention of: - possible pre-existing configuration, - way to look at it, - the more detailed help topic about how merge-tools configuration works. This should help users find they way.

subrepo: use subrepo shortid method to generate subrepo diverged promptchoice We were always using only the first 12 characters of the subrepo revision id when generating the "subrepo diverged" promptchoice. This is not necessarily correct for non mercurial subrepos.

subrepo: add shortid() method to subrepo classes This method takes an "id" (e.g. a revision id) and returns a "short" version (e.g. a short revision id). This will be used on the next revision to fix a small bug in the way that the text on the promptchoice shown when a subrepo diverges is generated.

localrepo: call _dirstatestatus instead of duplicating logic

workingctx: call _dirstatestatus in status Rip out the call from workingctx.status to localrepo.status.
