Log Message:
tests/make: proofread and clean up comments for function 'empty'

This prepares a refactoring for handling the function 'empty' in
conditionals like '.if'.

The function 'empty' is fundamentally different from all other functions
since it is parsed differently and passes its result on different path
than the other functions.  Splitting up these code paths will untangle
the control flow of parsing a condition like 'empty(VARNAME)'.  It will
also remove several ARGSUSED and MAKE_ATTR_UNUSED that make the current
code smell.
