discovery: use stable sort order in --new-branch warning
A Python set seems to do this already when you iterate over it, but
this should be considered an implementation detail and not something
we can rely on.
This also gets rid of an unnecessary string conversion -- the set
already contains strings.

# An example hgweb CGI script, edit as necessary
# Path to repo or hgweb config to serve (see 'hg help hgweb')
config = "/path/to/repo/or/config"
# Uncomment and adjust if Mercurial is not installed system-wide:
#import sys; sys.path.insert(0, "/path/to/python/lib")
# Uncomment to send python tracebacks to the browser if an error occurs:
#import cgitb; cgitb.enable()
