[PATCH 1/2] Fix generic typos in comments

["Ondřej Bílka" <neleai@seznam.cz>]

Hi, I wrote a tool that effectively fixes typos in comments and only in
comments.
It can be downloaded here:

https://github.com/neleai/stylepp

For typos you need identify them, write replacement dictionary and run
STYLEPP/script/stylepp_skeleton stylepp_fix_comment

Here generic dictionary is used that was taken from wikipedia.
