grep: problem with invalid argument to --context

[Daniel Resare]

When working with the swedish transaltion of grep i stumbled across this:

An obvious fix to an obvious problem in grep-2.5e.

Problem:

when grep is called with --context=NON-NUMERIC a simple bug in the
parametrs to error() causes grep to segfault.

Fix: 

diff -ur grep-2.5e.vanilla/src/grep.c grep-2.5e/src/grep.c

+      error (2, 0, "%s: %s", str, _("invalid context length argument"));
     }
 }
