Unnecessary end of line whitespace is generally frowned upon. In addition some
editors remove end of line whitespace automatically, making diffs hard to read.
This commit removes all trailing witespaces. Using some sed magic in bash:
find . -name "*.*" -type f -print0 | xargs gsed -i 's/[ \t]*$//'
It's more hassle than it's worth; hard to maintain, difficult to know what
exactly should be printed, and maybe wasn't all that useful to begin with.
Removing this should reduce the API necessary for new contributors.
