spaces before tabs create weird indentation

[joshinils]

I noticed weird behaviour with mixed spaces and tabs. I have enabled the whitespace visualization for clarity in the images.

one tab before the curly-brace, works as expected:

one space, a tab and the brace:

two spaces before the tab:

three spaces and a tab:

four spaces and a tab:

only four spaces, no tab, also works as expected:

Thanks for reporting. I've made some changes to handle this better, which you should be able to check on the dev builds.
