thanks; does that now solve all outstanding issues with stdin vs.
the module guis?  (when complaining earlier I had read the svn
log + emails out of order, and forgotten about the hung waiting-
for-input gui problem before posting; sorry for the noise)

can anyone think of a case where "-" would ever be used as an
arbitrary string, not meaning stdin?
I guess it is a similar probability to someone wanting to use a
literal "-" as a file or map name. g.message is all I can think
of, but that's not used in the gui menu.
