Summary: glob tilde expansion injects extra slash.

Initial Comment:
When a user account is created whose name has a dash in it, attempting to glob the account's home directory results in an extra slash appearing in the result path string:

$ useradd -b /home/ -p dash -m dash-user
$ tclsh
% info patchlevel
8.5.11
% glob ~dash-user
/home//dash-user

Ubuntu 12.04 64-bit.  Tclsh installed from default repository using apt-get.

Any testing you can do to determine whether the
bad results come back from the getpwnam* system
calls or not would be useful.

What does

file normalize [lindex [glob ~dash-user] 0]

return?

Message:
The system has an obviously non-normalized name for the user's home
directory? That's... well, not really Tcl's fault IMO (there are cases
where normalizing would be bad IIRC, such as automounters). My inclination
would be Wont Fix, but I don't claim to be an expert on what [glob] should
do here.
