amend: use "getcommiteditor()" instead of explicit editor choice This patch doesn't change any tests like as preceding patches, because editor invocation is already tested in "test-commit-amend.t".

commit: use "getcommiteditor()" instead of explicit editor choice This patch also eliminates "forceeditor" no more referred. This patch doesn't change any tests like as preceding patches, because editor invocation is already tested well.

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

backout: avoid redundant message examination Before this patch, "hg backout" examines "--message" and "--logfile" options explicitly. But this examination is redundant, because "commitfunc()" can receive the result of same examination by "cmdutil.logmessage()" in "cmdutil.commit()" through "message" argument. This patch avoids redundant message examination by "message" examination in "commitfunc()".

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

rebase: use "getcommiteditor()" instead of explicit editor choice This patch also enhances "test-rebase-scenario-global.t", because "hg rebase" hasn't been explicitly tested around editor invocation and "--edit" option. In the other hand, this patch doesn't enhance tests in "hg rebase --collapse" case, because it is already tested in "test-rebase-collapse.t".

histedit: use "getcommiteditor()" instead of explicit editor choice for "--continue" This omits (redundant) adding "\n' to "message", because: - empty line is inserted by "commitforceeditor", if editor is invoked - tail white-spaces are stripped at storing into chaneglog, otherwise This patch also enhances "test-histedit-edit.t", because "hg histedit" hasn't been explicitly tested around editor invocation and "--continue" option.

histedit: use "getcommiteditor()" instead of explicit editor choice for "fold" This patch doesn't change any tests like as preceding patches, because editor invocation is already tested in "test-histedit-fold.t".

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.
