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.
