This is a wrapper for codespell [1], a spell checker for source code.
Codespell does not compare words to a dictionary, but rather works by
checking words against a list of common typos, making it produce fewer
false positives than other solutions.
The script in this patch works around the lack of per-directory ignore
lists and some oddities regarding capitalization in ignore lists.
The ".codespellrc" file is used to coarsly filter out translation and
git files, as scanning those makes up for roughly 50% of the run time
otherwise.
