Don't bother too much about the limit anyway, it's more of a guideline,
and the first time the code was adapted to fit, it became totally unreadable.

And BTW, I think that the only reason for the bug you found precisely is
the introduction of these repeat_str/release_str local variables that seem
to be there just to reduce line length...

I agree, it looks like the initial intent was to have the strings
fit well within the union, but this is all but obvious.
