I am experimenting with using notmuch remotely over ssh (as in the
NEWS file; i.e. with a script containing ssh user@host notmuch "$@")
This is mostly excellent but it seems to get confused by some queries.
For example those containing brackets or just consisting of *. I think
this is a problem with ssh spawning a shell on the remote machine
which doesn't like the brackets or *.

Explicitly to reproduce the problem start notmuch with a remote
database using a script as above;
type * in the search box;
and emacs shows:
End of search results. (process returned 1)

If you search for "*" you get the expected results.
