I wish to fix the lisp/vc/vc-hg.el (vc-hg-working-revision) function with the `hg parent' command.Actually this function uses the `hg log -l 1' command that returns the last commited revision, not the last checked out revision. When checking out a specified revision with `hg update REV' the actual revision of FILE is returned by `hg parent'.vc.el:;; * working-revision (file);;;; Return the working revision of FILE. This is the revision fetched;; by the last checkout or update, not necessarily the same thing as the;; head or tip revision. Should return "0" for a file added but not yet;; committed.On success `hg parent' command returns 0 and prints the parent of FILE. For not registered, as added but not commited files, throws error code and prints a message, so could check the returning value to substitute the printed message with "0" as vc.el requires. Here it is proposed the catch/throw mechanism.2014-05-24 Santiago Payà i Miralta <address@hidden>* lisp/vc/vc-hg.el (vc-hg-working-revision): Fixreturning working revision instead of last revision.From 426ae4ae2f4ed6f26fc65bb5023fe79ba79686ae Mon Sep 17 00:00:00 2001From: Santiago Payà i Miralta <address@hidden>Date: Sat, 24 May 2014 00:20:19 +0200Subject: [PATCH] * lisp/vc/vc-hg.el (vc-hg-working-revision): Fix returningworking revision instead of last revision.

Good idea, thanks. But your patch's indentation was completely messed up (as well as placement of line breaks). I installed a cleaned up version into `emacs-24' (contrary to the previous patch which I installed into `trunk' since it was a new feature rather than a bug-fix).
