 Yes. Please find attached the patch implementing this proposal in the
least intrusive and simplest way I could find. It's not urgent per se, but
I'd really like this to be applied to master before the table_tool code is
merged as its tests now use this match_substr().

 I think the changes should be rather self-explanatory, but, of course,
please let me know if you have any questions about them. And I've tested
them by running "make unit_tests" which seemed[*] to work fine.

 Thanks in advance,
VZ

[*] I'm always a bit apprehensive with this make target, it gives so much
    output that it's quite easy to miss some error in it -- but the exit
    code was 0, at least.
