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)
