test-fetch: fix non-portable sed regex.
(s/...\+/.../ appears to be a GNU-ism: this test broke on OS X and
NetBSD. Changing \+ to * fixes it, although that is a slightly less
strict regex.)
Basic install:
$ make # see install targets
$ make install # do a system-wide install
$ hg debuginstall # sanity-check setup
$ hg # see help
