Typogrify 2.0.5 breaks Pelican installation

[sscherfke]

I’m using typogrify with pelican. My site used to build with typogrify==2.0.4 but breaks with typogrify==2.0.5.

Pelican gives me the warning unsupported operand type(s) for +: 'map' and 'list' (unfortunately without more details). And later, it all breaks:

Traceback (most recent call last):

I also posted this on the pelican tracker, because I’m not 100% sure who’s to blame here. https://github.com/getpelican/pelican/issues/1456

@sscherfke: Please test the fix in #34, which has been merged to Typogrify master.

[sscherfke]

Does not work. It now tries to add the result of two filter() calls and fails. Maybe using list comprehensions instead would solve this.

[justinmayer]

@sscherfke: Would you please test @barrysteyn's fix (#36) and let us know whether it addresses the issue you reported?

[sscherfke]

@justinmayer: It seems to work nicely. Got no errors.

[justinmayer]

Great. Thanks for helping out with testing!
