[bug-grep] Warnings from m4 files patch

[Tony Abou-Assaleh]

Attached is a patch that does the following:

        * Eliminate underquoted definition warnings from m4/*.m4 files.
        * Use patsubst instead of m4_patsubst in m4/header.m4.
        * Use regexp instead of m4_regexp in m4/header.m4.

Not an interesting one, but someone's got to do it. Please review and
comment.

Cheers,

TAA
