[gollem] change directory to ~foo or ~/foo

[kevin mcgowan]

One of the features we'll need from gollem before we could deploy it on  
our campus is the ability for users to enter strings like  
"~foo/Public/html" or "~/Mail" as arguments to the "change directory"  
command.  I've attached a context diff against what I believe to be CVS  
head of my take on how ( and where ) such ~ handling might work.

I know it is somewhat uncouth to join a list and then immediately  
submit a patch, but I have to introduce myself somehow. :)

uncouthly,

Kevin
