I generally use spaces instead of tabs for code. This doesn't work for Makefiles though, which require tabs for separators. Is there a way to configure Sublime Text 2 to use tabs for Makefiles only?
EDIT: spaces->tabs for makefiles
If you make a file called Makefile.sublime-settings in your Packages/User directory, and put this in it:
then it should override your user settings for makefiles only.
