My thought was actually the reverse, that patch should somehow consult
with the filesystem (i.e cygwin) to see if a given string is a
relative path rather than somehow figuring it out itself. However, in
retrospect that would require that cygwin has this API and also
changing patch which I assume is avoided when possible for cygwin
ports?

Fair enough (the diffutils manual is dated 1993). Should I try and
report it somehow? I have no idea where to report GNU doc bugs.
