Subject: [PATCH] grep: warning to be uninitialized with -Wall

If `lint' macro isn't defined, kwset.c is warned to be uninitialized
with -Wall.  Of course, even if it's warned, there is no operational
problems.  However, I can't find any reasons that `accept' variable
should be uninitialized.  So fix it.
