check-commit: make foo_bar naming regexp less greedy

\s is equivalent to the character class [ \t\n\r\f\v]. Using \s+ in
a regular expression against input with multiple lines may match across
multiple lines.

For the regexp in question, "\+\s+" would match "+\n " and similar
sequences, leading to false positives for functions that were included
in diff context, after a modified hunk.

    try:
        print f, '->', os.readlink(f)
    except OSError, err:
        if err.errno != errno.EINVAL:
            raise
        print f, 'not a symlink'

sys.exit(0)
