Minor tweaks/fixes
==================
* Do not use variables where they are not needed
* Do not duplicate the same test
* Unset multiple variables with the same command instead of 2
* When deleting empty DISTDIR subdirs use -mindepth 1 so that it will not
  error out if the directory is totally empty.
* Unset more stuff after it is no longer needed
* Update some comments to match the current state of the code
* Remove some stuff that cannot be reached any longer

Performance enhancement
=======================
* In read_distinfos*() use while read instead of grep. Avoids the fork
  and cuts the total time for that feature 25%
