link encoding problems

[sspross]

if we insert a link including an ampersand like:

http://maps.google.ch/maps/ms?msid=215832598504455117006.0004a5e6c4bfdf2e1844b&msa=0

pennyblack will encode this into:

http://maps.google.ch/maps/ms?msid=215832598504455117006.0004a5e6c4bfdf2e1844b&msa=0

but lose it while redirecting and in the end points to:

http://maps.google.ch/maps/ms?msid=215832598504455117006.0004a5e6c4bfdf2e1844b

what in this case doesn't work...
