description:
Fix compressed server accesses.
According to http://cvs.savannah.gnu.org/viewvc/ccvs/src/?root=cvs
this was broken between revs 1.29 and 1.32 for a perion of 4 months
about 4 years ago.
Not sure at all why/how we have the broken version.
Our old code, the latest gnu code and this fix all differ slightly,
but have the same effect.
