This time everything looked good to me and I queued them into the fixes
branch since they address a real corner-case bug. I finally decided not
to change your comment for '/*' on a single line because it turns out
that the file in question almost exclusively uses the shorter, net-style
comments like you did, and you were probably inspired by the surrounding
ones.

Many thanks for your work and your patience ;-)
Willy
