I didn't realise it was that long, but one pair of files to diff takes
128 bytes of that.
$ wc -c <<\E

128
So that's space for 1024 pairs. (Doesn't envp take some up too?) That
doesn't seem enough for diffs between revisions, but good enough for
most uses that people will get caught out when it fails.
$ bzip2 -dc patch-2.6.10.bz2 | grep -c '^diff '
5384
Cheers,
Ralph.
