commit 35052b96232810cbf0d91a4f1d1d3ff25a142fd0
Author: Panu Matilainen <pmatilai@redhat.com>
Date: Mon Mar 15 11:54:55 2010 +0200
Add an enhanced argvSplitString() function for splitting strings to argv's
- Returns the newly created argv instead of useless "this always returns 0"
- By default make a "real" split, including empty strings
- Flags argument allows controlling behavior, for now only flag is to
preserve argvSplit() behavior but leaves room for future enhancements
such as quoted splitting etc

Avoid eating empty lines in spec %prep section (RhBug:573339)
- In spec %prep context empty lines don't usually matter but they can
be significant in eg here-documents.
- Fixes regression from commit 94ff22b129aeb31c38848231e40f87aa4a5613a1
