Good, thank you.  Also to Michael for reporting the bug so precisely.

No it doesn't, I just verfied by code inspection.  The old version was
allowed to "return;" everywhere in the function in question (and does
in this error case).  OTOH, when porting Doug's new version, which
only has a single exit point, I made a copy-and-paste error (a closing
brace was wrong), which is corrected by the patch.
