[patch] removing misplaced periods in --help

Attached patch removes three periods from the 'grep --help' message
and changes one line a bit to match the earlier TYPE and ACTION.

The second patch goes a bit further, it adds a few semicolons to
make it slightly clearer that the explanation doesn't stop there,
and rearranges a few lines.
