Thanks Bjoern. Good point, and as it was already a script (rather than a
one-liner) I've broken it up a bit as you suggest. I just made one fix,
as noted below. Without the double quotes it treated the svn output as
multiple parameters, not a single string.

Not in this case; the point of this script is to tell me when users who
are not svn-aware have changed the web site. (I already use post-commit
to tell me what the svn users are changing :-)

  if [ "$svn_status" != "" ]
or:
  if [ -n "$svn_status" ]
