It sounds like the OP wants a "indentation is not a multiple of N"
error/warning which would be a more generic (and as you state, look
weird doing so).  I wouldn't expect pep8 to do it, since its goal is
to align with pep8.  But I could see some of the other checkers
having a command-line option to set the expected indentation.

Otherwise, one might just do something like

  sed -n '/^\(  \)*\</!{=3D;p}'

which will print the offending line numbers on one line followed on
the next line by the offending line's contents.
