I would assume that glob expressions would obey the semantics of the
environment where the working copy was checked out:

The question is wether you use the requirement that the glob
expression match the file name or the file name match the glob
expressions.

I just checked and the Mac OS X terminal these are not equivalent --
glob expressions are case sensitive even on a non-case sensitive file
system:

sgs$ echo this is foo > foo.txt
sgs$ echo this is BAR > BAR.TXT
sgs$ ls
BAR.TXT foo.txt
sgs$ ls *.TXT
BAR.TXT
sgs$ ls *.txt
foo.txt
sgs$ ls foo.txt
foo.txt
sgs$ ls bar.txt
bar.txt
sgs$ cat foo.txt
this is foo
sgs$ cat bar.txt
this is BAR
sgs$

But note that the last "cat" succeeds because the file system is case
insensitive.

Not sure which obeys the "principal of least user astonishment", but
I'm leaning toward obeying the semantics of the filesystem where the
working copy is checked out.

Another sane choice would be to default to insensitive with an option
to force sensitivity.

YMMV,
