This way you are modifying your sources-files.

This is bad for 2 closely related reasons:
- Sources should be considered read-only in general.
- This is likely to break on "repeated runs": A previous run modified
your sources in such a way, your next rpmbuild run is not unlikely to
fail.

You will want to work on copies of your SOURCEX's instead of SOURCEX
directly.
