Your earlier http://thread.gmane.org/gmane.comp.version-control.git/96464
made a lot of sense to me.  The request "refname:short" cannot be for use
by scripts (well, scripts may pass it to for-each-ref but that has to be
for final consumption by humans wanting to view the names in a format not
overly long, as opposed to scripts using for-each-ref to extract
unambiguous names to be used for further processing, in which case they
would be using "refname" without ":short"), so I do not see "change the
current default behaviour" is a bad thing at all.  If anything, it is an
improvement, isn't it?
