[PATCH 2/2] git-am: force egrep to use correct characters set

[Christian Himpel <chressie@googlemail.com>]

According to egrep(1) the US-ASCII table is used when LC_ALL=C is set.
We do not rely here on the LC_ALL value we get from the environment.

I don't know if this kind of patch is desired, but according to egrep(1)
it's not reliable to use the range expression with different character
sets than US-ASCII.

So this patch forces the usage of US-ASCII.

chressie
