Thank you, now I understand.
I really  completely misinterpreted your "very long standing"
above.

Hence I do apologize for the negative connotation of the
above... and thank you again -- in the name of all involved --
for reporting the bug here!

BTW: I've committed  svn rev 68519  
about ten minutes ago which does fix the bug (simply applying your good advice)
and contains a regression test.

Thank you once more, Radford!
