Ah, and now I see why add-modelines messed up the last line.
add-modelines checks the first 6 characters of the line to determine if
there's a modeline present. It uses the beginning of the to-be-set
modeline to determine the answer to "what is a modeline?". However, that
line in your edge-case has "vi:set", rather than "vim:set", so
add-modeline didn't see it. I hope that this edge case doesn't have
lurking partners in crime elsewhere in the codebase. I suppose I should
start some urgent grepping to see?
I'll have to consider whether that's worth lowering the check to 5 and
risk picking up comments as modeline "false-positives", or just ask you
to change those by hand before running the script. ;)
