[Koha-devel] Splitting bugs into multiple patches

Dear Koha devs, Another question. Is there any rule of thumb into how many parts a bug should be split? For example, if I add a few lines in a perl module, modify two intranet HTML templates and an OPAC HTML template. Should this be divided into three commits? Or just one, since you can't easily test the perl module without the templates? Or one part for the pm and intranet changes and another for the OPAC changes? Thank you! Holger
