Thanks for this -- I didn't take it directly, because looking closer at the
code I realized that using clean_header() was wrong here in the first place,
so the code could be simplified to only ever use the raw regex. I've pushed
the commit to master and will try to release 0.8.1 soon so other projects pick
this up as well.

Thanks!
