Bug report:

./gnuize.sh: line 37: syntax error near unexpected token `else'

Some change is done on Revisions · GNU-ize Mac OS X El Capitan. Apart from the bug fix, there're also some cosmetic change, e.g. the .bash_path is now more readable; through printf instead of echo.

Note: I original forked this as another gist, and now imported it to a repository in https://github.com/ickc/GNU-ize

Sadly GitHub doesn't show that it is a fork of this gist. Credits will be given to the original author in the README. @TorgeH: do you have any license you'd want to use? If no I'd just choose GPLv3 (appropriate because this script is about GNU).
