This very well could be only be needed in virsh, it just seemed like
util/util.c was where it could have the least duplication of code.

isatty() produces the correct behavior in all cases but the first one
you mentioned, ie running "virsh define", which will not wait for input
with the patch as it is.

I see the ctl->imode parameter used in main() to determine the
interactivity of the session, though that is only accessible at the
cmdOPERATION level, not in virFileReadAll().  Maybe (yet) another read
wrapper local to virsh.c that would check the ctl->imode if no path is
offered, and make a decision from there.

Thoughts?
