Spf13 VIM: Not to eat up tabs on empty lines on save

Question

The wanted behavior for many on Spf13 VIM is to eat up any whitespace or tabs on an empty line. I am working on an existing project, and I've got a lot of these changes in the change log:

How can I stop Spf13 VIM from deleting these tabs on empty lines?

Edit:

Never mind, it does work. Answering my own question now.

Answer 1

Found this in the Spf13 .vimrc file:

" To disable the stripping of whitespace, add the following to your
" .vimrc.before.local file:
"   let g:spf13_keep_trailing_whitespace = 1

After adding that it worked, also for tabs.
