Being fairly new to this group I have a question. Is it expected that
changes like this will get folded back into the main source distribution or
do they remain idividual efforts? Will you have to apply the same patches
on the next release etc.? How are decisions like this made? Is it simply
a consensus and then cygnus takes the best ideas/suggestions and then
merges them in when they get the opportunity?

I like it - now to change my aliases :-)

True, also as you said, if there are two possible matches differentiated by
case then it should go for the case matching one first. That'll cut down
on the number of times that the option will need to be toggled.
Thanks for the follow up - Guy
