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.)
#!/bin/sh
hg init a
hg clone a b
cd a
echo '[paths]' >> .hg/hgrc
echo 'dupe = ../b' >> .hg/hgrc
hg in dupe | fgrep '../'
cd ..
hg -R a in dupe | fgrep '../'
true
