Not trying to start a flame war, but I am on the tabs side of the discussion. Most companies have rules about tabs/spaces (we use spaces, much to my chagrin), and it's pretty easy to set a rule.

I code in Go a lot now, and Go ships with gofmt, which formats your code for you (uses tabs by default). There are similar tools for every language I've used. This can be set in a pre-commit hook (or whatever the terminology is for non-git scms), so it's not really an issue. We do this, and it works like a champ.
