bug#21404: 25.0.50; vc git mode-line 'font property cut off

[Mark Oteiza]

Hi,

The following commit

http://git.savannah.gnu.org/cgit/emacs.git/commit/?id=21d6414a4

breaks fontification of the vc git mode line string.

  (vc-default-mode-line-string 'Git "~/foo/bar")
  => #("Git-a071fefe36be6069f5b66467767b9e88c73a5bf6" 0 44 (help-echo "Up to 
date file under the Git version control system" face vc-up-to-date-state))

  (replace-regexp-in-string
   (concat "a071fefe36be6069f5b66467767b9e88c73a5bf6" "\\'")
   "master"
   (vc-default-mode-line-string 'Git "~/.zshenv")
   t t)
  => #("Git-master" 0 4 (help-echo "Up to date file under the Git version 
control system" face vc-up-to-date-state))

So, only "Git-" is given the face, instead of the whole "Git-master"
