[RFC PATCH 0/3] bug #30771 and related

[Paolo Bonzini]

Hi all,

this is a patch to fix the worst part of bug #30771 (the segfault).
The segfault could also be reproduced by passing a zero-sized file or
/dev/null as the input file, and I opted for the latter.

I added a second test, which I marked as an expected failure, to test
that grep fails when a directory is passed to "grep -f".

The problem is that I could not make the test fail, because the segfault
is strangely not seen if the "grep -Fif /dev/null" command is run from
a script.

Help completing the patch is thus welcome (together with reviews for the
other patches that have been posted).

Paolo
