This is a feature of your favorite text editor. Not all have it.

See, this is not the only place on this document using :doc:``. It is just
the one using it wrong:

-

That's said, automarkup.py has a rule to convert Documentation/<foo>.rst
into :doc:`<foo>`. So, an alternative approach would be to convert
treewide all :doc:`<foo>` into Documentation/<foo>.rst and add something 
at checkpatch.pl to recommend to avoid :doc: notation.

Tests are needed, though, to be sure that automarkup.py won't miss
something, as the regex there might require tweaks to cover some
border cases.

Thanks,
