I meant something like this:

If there's override_dh_FOO, but dh_FOO is not in 
data/debhelper/dh_commands, and there's a known dh_* command that is 
within close edit distance to dh_FOO, then that's probably a typo.

This would be similar to how we detect typos in DEP-5 copyright files 
(see checks/source-copyright.pm, grep for field-name-typo).

This would let us find more creative misspellings, like the infamous 
dh_auto_instakk[0].
