HG, git and others actualize the modeline when commit form the command line

[Uwe Brauer]

Hi

I tested this in mercurial.
If I commit a change via vc-next-action
the modeline gets actualized.

If I make the commit from the command line (using Ubuntu 16.04) the
change is not reflected in the modeline I have to close and reopen the
file.

I tried out 

(force-mode-line-update) 
via M-:
but it did  not change the modeline

Any idea what to do (besides using vc-next-command and friends).

Regards
