Reading the history, how about this.

get_mataintainer.pl outputs a single prefix, if multiple files have the same prefix it works, if they don't its an error.

Another script 'commit_one_file.sh' does the call to get_mainainter.pl to get the prefix and be called by run-clang-tools.py to get the fixer specific message.

Defer minimizing the commits by combining similar subsystems till later.

In a steady state case, this should be uncommon.

Taken care thanks!
