Is the locale command that portable?.
I'm not sure this is even necessary in the cases where it is just calling
svnadmin help or svn help rather than svn status.

Originally, _subversion set LC_MESSAGES for these commands but LC_ALL
overrides LC_MESSAGES. Would it be better to do it as follows:
  LC_CTYPE=${LC_ALL:-${LC_CTYPE:-$LANG}} LC_ALL= LC_MESSAGES=C _call_program ...

Or should we change the patterns so they'll work even with output in
other languages. For svn status, the changelists are introduced with
lines starting '---' and for svn help, sub commands all start with
three spaces so that may be the best option.
