bug#19161: 24.4; vc-mode reload on commit - don't jump to start of buffer

[Ed Avis]

Use vc-mode to edit a file in a Subversion working copy, where the file
has the property svn:keywords set to 'Id' and contains a magic $Id: $
string.  On committing with C-x v v, the file will be reloaded after the
commit, and point jumps to the top of the buffer.  This is annoying
because you lose the place you were working at.

It is necessary to reload the file on commit because the version control
system will have modified the Id: dropping, but this is a small change
that doesn't affect the position of the rest of the text in the
document.  (The only version control post-commit operation that might
make a significant difference to text position is the old practice of
including the whole Log: in the file, but only older systems like RCS
and CVS support that.  Even then, the Log: is often appended at the end
of the file, so will not affect the current cursor position.)

When committing, Emacs should continue to reload the file contents
afterwards, but it should save the current point and not move to the
start of the buffer after the reload.
