Often, if a function is defined but unused, the ‘define’ line will be
marked as hit whereas the rest of the function will remain red–but
that’s OK since strictly speaking the ‘define’ line /is/ executed.

However, it could be that the code coverage code is buggy.  If you find
obvious errors and can reduce them, I’d be happy to look into it.

Thanks,
