Subject: Enhancement request: Make show_help a bool

Hi, why is "static int show_help on line65 in src/grep.c a int?
It's value is only set once in "src/grep.c:2704" to a 1.
Wouldn't it be better to make it a bool?

As this my first mail to a GNU project ever I don't know how to properly 
contribute code, are there methods like Pull Requests or do I need to 
submit a patch the traditional way through a diff on a mailing list?

Greetings and Happy New Year,
