Subject: [PATCH] Revert "Fix logic error in macro file reader"
This trips over the following comment line in macros.python-srpm,
preventing all subsequent macros from loading:
Temporarily revert to let Python builds continue while looking for
proper fix.
This reverts commit 75275a87cff04da65d3557f2c40ea2b526528c4c.
