grep: avoid sticky problem with â-f - -f -â
Inspired by bug#50129 even though this is a different bug.
* src/grep.c (main): For â-f -â, use clearerr (stdin) after
reading, so that âgrep -f - -f -â reads stdin twice even
when stdin is a tty. Also, for â-f FILEâ, report any
I/O error when closing FILE.
