def monkey_patch_blockdiag():
"""Monkey patch the blockdiag library.
The default word wrapping in blockdiag is poor, and breaks on a fixed
text width rather than on word boundaries. There's a patch submitted to
resolve this [1]_ but it's unlikely to merge anytime soon.
In addition, blockdiag monkey patches a core library function,
``codecs.getreader`` [2]_, to work around some Python 3 issues. Because
this operates in the same environment as other code that uses this library,
it ends up causing issues elsewhere. We undo these destructive changes
pending a fix.
TODO: Remove this once blockdiag is bumped to 1.6, which will hopefully
include the fix.
