Yes - I could imagine in certain cases it might be useful to squash several
patches together to improve readability here.

But before you change some code - please look at how it has looked and do not
put problem which were already resolved.

Few notes for script writing:  use  "$VAR"  (since path may contain spaces)
Preferred way for using shell test is  'test '  instead of []
