I see how it makes sense to add a tab to align with the previous line
of code, as it will always look similar in all editors, no matter how
their tab character is set up to be.
However, adding more tabs will just mess up editors that are not set
up with 8-space width tabs.
Is this a bug in checkpatch.pl, or are we saying everyone should have
their editor set to 8-spaces width tabs?
