[Samba] Samba mounted home shares will break many applications

[Bob Smith]

To follow up on Unix Extension verification I ran the following on a
CIFS mounted share:

$ > "testfile\/"
bash: testfile\/: Is a directory
$ > "testfile:"
bash: testfile:: No such file or directory
$ > "testfile\:"
bash: testfile\:: No such file or directory
$ > "testfile*"
$ > "testfile?"
$ > "testfile\""
$ > "testfile<"
$ > "testfile>"
$ > "testfile|"
$ ls -l testfile*
-rw-r--r-- 1 rwsmith rwsmith 0 2009-06-22 19:21 testfile<
-rw-r--r-- 1 rwsmith rwsmith 0 2009-06-22 19:21 testfile>
-rw-r--r-- 1 rwsmith rwsmith 0 2009-06-22 19:21 testfile|
-rw-r--r-- 1 rwsmith rwsmith 0 2009-06-22 19:20 testfile?
-rw-r--r-- 1 rwsmith rwsmith 0 2009-06-22 19:21 testfile"
-rw-r--r-- 1 rwsmith rwsmith 0 2009-06-22 19:20 testfile*
-rw-r--r-- 1 rwsmith rwsmith 0 2009-06-22 19:19 testfile\

As you can see 7 of the reserved characters can be used within
filenames--the slash "/" character I known why, but why not the colon
":" character?!?!

P.S. I have also validated that this an issue when using a client with
Fedora 11 + CIFS.
