Unfortunately print-escape-newlines does not quote tab, only newline
and form-feed. Which in my opinion is a bug. To fix this just copy 5
lines in print.c at line 1667 and replace form-feed with tab. (I have
just done that in my patched copy, but it is easier to do this by hand
then to use a patch.)

Is there any objections to this change?
