I think it was actually correct, if you follow through the logic from
the parent block.

The version is parsed as:

	$VERSION =~ /(.*?)([a-yA-Y][a-zA-Z]*|\d+)([+~])?$/i;

with $start being set to the first captured group. Some quick testing
indicates that this results in, for example:

    1.2-3+deb9u1 => 1.2-3+deb9u
    1.2-3~bpo90+1 => 1.2-3~bpo90+

    (Whether that's logical is an entirely different question.)
