Description:
------------
Darwin 9's sed is broken, causing ./cvsclean to remove a bunch of bogus file names. Occurs in 5.2, 5.3, and HEAD. Specifically, when catting .cvsignore, cvsclean gets a list like this:
Makefile.objects Makefile.f agme ts Makefile acco fig.h aclocal.m4 autom4te.cache bsd_co ve ted buildmk.stamp buildco f.stamp co fig.h.i  co fig.cache co fig.log co fig.status co fig_va s.mk co figu atio -pa se .c co figu atio -pa se .h co figu atio <and so on>

Patch that fixes in all three:
