KeyError after adding a directory to exclude patterns

[JulienPalard]

I noticed I had a .venv in my output so I added .venv to ignore_directories, but then I got:

KeyError: '.venv'

with sigal, version 2.4

I found a problem in the ignore_directories logic, hopefully 114f4e2d42c3fb3526b47418a1cd1de44f948b44 should fix that.

[JulienPalard]

It does not looks enough, I'm tried the patch and I'm now getting:

KeyError: '.venv/lib64'

@JulienPalard - I couldn't reproduce (see commit above), it works for me with ignore_directories = [".venv*"]. Maybe you forgot the star ?

[Lucas-C]

For the record, I reproduced the bug by setting ignore_directories = ["venv/*"] with a virtualenv directory named venv.

Removing the slash from the pattern solved the issue in my case.
