Yes, of course one must weigh cost and benefits. In this case the patch not only 
improved performance, it also made the code smaller and in my opinion more 
readable: the total source code size shrank by 1775 bytes. Source-code 
improvements add up too, and we should encourage them even if they're small, as 
they are a welcome partial antidote to the bloat that often afflicts older 
software projects.
