Test for bug 1192 - brace expansion.

Commit 968d1c3 (Portability) introduced a bug with some very POSIX
compliant shells (eg dash), which don't do brace expansion.  So add a
test for that.

The test runs by adding a new protocol in Uri, sh+cp://path/.  This
protocol is not intended to be used normally, but is only for testing
the push and pull code.
