bug#39678: 'grep --ignore-case --color' does not always color the matches

so is my patch correct? Without my patch re_string_peek_byte() is not
executed - and this is the function that is executed (and where the match
is found) when "--ignore-case" is not enabled. With my patch grep is able
to match the '\a' while still preserving the correctness for other cases.
For sure some tests would be helpful but from what I checked my patch is
not breaking anything else while adding the correct match for '\a' case.
If you still think the patch is wrong, could you please point me in the
right direction? Maybe you could point me where it's not preserving
