histedit: pass 'editform' argument to 'cmdutil.getcommiteditor'
This patch passes 'editform' argument according to the format below:
EXTENSION[.COMMAND][.ROUTE]
- EXTENSION: name of extension
- COMMAND: name of command, if there are two or more commands in EXTENSION
- ROUTE: name of route, if there are two or more routes for COMMAND
In this patch:
- 'edit', 'fold', 'mess' and 'pick' are used as COMMAND
- ROUTE is omitted
'histedit.pick' case is very rare, but possible if:
- target revision causes conflict at merging (= requires '--continue'), and
- description of it is empty ('hg commit -m " "' can create such one)
In the code path for 'histedit --continue' (the last patch hunk),
'canonaction' doesn't contain the entry for 'fold', because 'fold'
action causes:
- using temporary commit message forcibly, and
- making 'editopt' False always (= omit editor invocation if commit
message is specified)
Mercurial's documentation is kept in reStructuredText format, which is
a simple plain text format that's easy to read and edit:

It's also convertible to a variety of other formats including standard
UNIX man page format and HTML. You'll need to install Docutils:
