Tabs in source delimited by code tags

Would it be possible to present source code so that tabs are replaced with space fill to the next tab position?

I understand that everyone has their own preference (I prefer 3), but tab "stops" every 3 or 4 columns generally work better for C/C++ than every 8 columns...

I usually run a TABs-to-spaces function in my editor (Notepad++) before posting code.

AFAIK 4 columns is pretty standard for code.
