exit 2 (rather than infloop) when an input file is also on stdout
This avoids a potential "infinite" disk-filling loop.
Reported in http://savannah.gnu.org/patch/?5316
and http://savannah.gnu.org/bugs/?17457.
* src/main.c: Include "quote.h".
(out_stat): New global.
(grepfile): Compare each regular file's dev/ino/etc.
with those from the file on stdout (if it too is regular).
(main): Set out_stat, if stdout is a regular file.
* src/system.h: Include "same-inode.h".
(same_file_attributes): Define. From diffutils.
(SAME_REGULAR_FILE): Define.
* bootstrap.conf (gnulib_modules): Use quote, not quotearg.
