> Getting the indentation right should be the least of your worries if you have a good editor (and don't do something like mix spaces and tabs, which I think everyone is in general agreement with across all languages).

Nope. Tabs are for indentation and spaces are for alignment. It's precisely because of non-good (or maybe non-smart) editors that people can't be bothered acknowledging or practicing this distinction and end up using spaces for both.

I was mainly talking about mixing tabs and white space for indentation. Many people set their tabs equivalent to different numbers of whitespace, so when the whitespace and tabs mix, it becomes an issue if the previous developer had tabs set to 2 spaces, but you have them set to 4.

Conveniently, any editor that can properly deal with tabs will have an easy time dealing with semantic leading spaces.
