Have you noticed any issues with, e.g. Ubuntu 16.04 using this script?
What I've found is that, if the
git diff --cached --name-only | egrep '(\.(mm|m|h|cpp|json)$)'bit returns no matches, the result of the rest of the line depends on all the files that have changed. So, let's say you have a load of .cpp files, and a .cproject file. If you've only changed the .cproject file and staged it, and it has tabs in it, it will be picked up in the xargs processing and your commit will be rejected.
