print returning via REPLY

print returning via REPLY

[Sebastian Gniazdowski]

Hello
The code of print builtin is rich into various states. I was thinking
about adding REPLY support to it, but it seems to be too complicated
for me. Maybe someone has better overview of the various states of the
function, and could add the REPLY support? Maybe it isn't actually
hard? My motivation behind this is to be able to quickly expand tabs -
doing a fork to read print's output is slow.

Best regards,
Sebastian Gniazdowski

This would require moving the first block of HAVE_OPEN_MEMSTREAM stuff
(and it's #else, of course) from below the OPT_HASARG(ops, 'x') test
to above it, so that the result of the tab processing is captured;
and then figuring out how/where to do the corresponding cleanup (maybe
just a "goto" that jumps to the near the end of the function).

Aside, the doc doesn't actually say that -x can't be used with -z/-s/-f
(and print doesn't complain about the attempt) even though that is the
case.
