One set of questions before I decide whether to address this in 2.62...

If CR is _not_ the EOL marker, then how would CR appear at the end of the
line? Where are we doing input into $tmp/subs1.awk that could create a
spurious CR if the platform does not use CR? And if CR is not EOL, then
do we really need to escape intermediate CR rather than treating it as a
literal character?
And according to this patch, if CR _is_ the EOL marker, then just using mv
works. So why not use mv unconditionally?
