Summary: glob with drive relative path fails

Initial Comment:
Compare these two glob commands given
on Windows 2000 from the MKS Korn shell

771 C:/p/airvid/img/c2> tclsh84
% glob /p/airvid/img/c2/*gif
/p/airvid/img/c2/12.00.00f.gif /p/airvid/img/c2/12.00.00t.
gif /p/airvid/img/c2/12.00.01f.gif /p/airvid/img/c2/12.00.0
1t.gif /p/airvid/img/c2/12.00.02f.gif /p/airvid/img/c2/12.0
0.02... (more files truncated)
% exit
773 C:/p/airvid/img/c2> tclsh85
% glob /p/airvid/img/c2/*gif
no files matched glob pattern "/p/airvid/img/c2/*gif"

% glob c:/p/airvid/img/c2/*gif
c:/p/airvid/img/c2/12.00.00f.gif 
c:/p/airvid/img/c2/12.00.00t.gif 
c:/p/airvid/img/c2/12.00.01f.gif 
c:/p/airvid/img/c2/12.00.01t.gif 
c:/p/airvid/img/c2/12.00.02f.gif c:/p/airvid/img
/c2/12.00.02t.gif c:/p/airvid/img/c2/12.00.03f.gif 
c:/p/airvid/img/c2/12.00.03t.gif 
c:/p/airvid/img/c2/12.00.04f.gif 
c:/p/airvid/img/c2/12.00.04t.gif 
c:/p/airvid/img/c2/12.00.05f.gif ... (more files truncated)

It seems quite apparent that the windows glob no longer
works right on patterns that begin with slash.

This install was built from snapshot file: 
tcl-20040213.tar.gz

Regards and thanks,
Roy Terry

Unfortunately, volumerelative paths are hardly tested in the
test suite (I assume you would have run the test suite
yourself before reporting this anyway?).

8.4 therefore has a number of problems with such paths --
some stuff works, some doesn't.  In particular, vfs support
for volume relative paths is v. poor in 8.4 (but ok in 8.5).

This will work for me in my present usage. 
The fix which adds a drive component doesn't "feel" right to 
me and I wonder if it will create incompatibility bugs upon 
migration from 8.4 to 8.5.  BTW, is this behavior covered in 
the test cases?

I have a fix for this, but in the same way that glob
'foo\bar' gets converted to 'foo/bar' in the list of
results, it will convert your 'glob /p/airvid' to list
results as 'C:/p/airvid ...'.

Is that ok?

I can reproduce it, so I'll look into fixing it.
