spec-cleaner crashes when 'cleaning' bundle-lang-common spec files

[DimStar77]

Spec-cleaner is being used in order to get the bundle-lang-common (autogenerated) spec files somewhat readable.

Since a recent update this seems no longer to work. My history of spec-cleaner:

2017-05-22 14:33:43|install|spec-cleaner|0.9.5-1.1|noarch||repo-oss|c6b8e5b39062beaa7784c0abd569b636027940aa| 2017-06-13 13:41:24|install|spec-cleaner|0.9.6-1.1|noarch||repo-oss|877daf3bd821540723b3957b42e2660764c67e44| 2017-06-17 15:52:02|install|spec-cleaner|0.9.7-1.1|noarch||repo-oss|5229d346319f696e06a1d6620e7a5fdd7283ec37|

The last time I can claim that this was working must be June 12 (when the package was last updated)

How to reproduce:

osc co openSUSE:Factory/bundle-lang-common cd openSUSE:Factory/bundle-lang-common spec-cleaner bundle-lang-common.spec usually the script is started with -i, but it makes no difference)

This leads to this error:

Thanks! Hot-patched my local install based on your diff and this indeed works now
