I tried ls "**" and "ls ***" on my system here and couldn't tell any
difference from "ls *". I also don't seem to know how to work "RE:". I use
bash, which isn't an uncommon shell.

I don't think thats necessarily a bad idea -- in fact, somebody already
mentioned the tutorial, though I would like for us to consider the unlikely 
possibility that somebody would gloss over documentation.

However, later in your post you mention possibly having to do this
expansion within Bazaar-NG itself for windows. If that's the case for
cmd.exe, then isn't it the case as well for bash?

If your meaning is include support for patterns that come from ZSH and are
rarely supported elsewhere, then that's more of a problem. I think its
so-so to allow something that most platforms support (e.g. symlinks)  and not
a good idea ("/" as a filename character) when most platforms don't.

I'm particularly interested in this hypothetical question: If Martin used
zsh (he may), adds a "RE:..." pattern to the bzr tree, will I be still be
able to work safely without changing shells?
