You can do everything you need to in vim.

I would either revert the source back to the original formatting and
commit that, or make a commit on just the format changes.
Key settings in vim you should familiarize yourself with are :
and also familiarize yourself with the "retab" command.
My style/rule/preference is:
tabs are always 8 spaces (ts=8) except for the moments you need to
change the setting so that :retab creates the proper
indentation levels (then revert back to ts=8)
use shiftwidth and softtabstop to control indentation levels.
I like a 4-space indentation, so I use sw=4 and sts=4.
never use tabs (:set et)
The retab command converts the indentation between tabs and spaces and
does so according to how et, sw, sts, and ts are set. The details are
in the manual (:help).
