Here is a result of a quick audit (of 1.8.0.x codebase).
As xwrite() will not be splitting a single-byte request, the patch
to cat-file is more or less a theoretical fix, but if writing the
date string can fail in I/O error, writing a terminating LF after it
can fail the same way, so we should be consistent.
Everybody supports the side-band tranfer these days, so the patches
to receive-pack and upload-pack are also theoretical fixes, I
think. Note that in the more recent codebase, safe_write() is gone
and we use write_or_die() instead in upload-pack.
