nope, upper-case -I is also already taken.

Just to clarify: the only ls(1) options taking a pattern are:

  $ ls --help | grep PAT
        --hide=PATTERN         do not list implied entries matching shell 
PATTERN
    -I, --ignore=PATTERN       do not list implied entries matching shell 
PATTERN

I'd assume that these options are very rarely used, and therefore I have
the impression that you meant something else: I guess you mean the call
like:

  $ touch somefile someother
  $ ls some*
  somefile someother

Now, this is nothing we can change in ls(1) since the calling shell already
does the pattern matching and calls ls(1) with the expanded list of files.
One can see this with:

  $ echo ls some*
  ls somefile someother


Have a nice day,
