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.

# A portable replacement for 'seq'

# Usage:
#   seq STOP              [1, STOP] stepping by 1
#   seq START STOP        [START, STOP] stepping by 1
#   seq START STEP STOP   [START, STOP] stepping by STEP
