comparing two files, where only one file is missing the final newline
character. This undoes revisions 1.3 and 1.4, returning 'diff' to how
it behaved before July 2000. We can do this now because our version of
'patch' was modified (just before 4.6-release) to understand what to do
with that line. This marker is the same one generated by 'diff' under
netbsd, openbsd, darwin, and linux (and any OS with "gnu-diff" installed).
