delta-find: drop the temporary indent
Now that the complicated change is made, we can do the noisy one.
Function to test discovery between two repos in both directions, using both the local shortcut
(which is currently not activated by default) and the full remotable protocol:
$ testdesc() { # revs_a, revs_b, dagdesc
> if [ -d foo ]; then rm -rf foo; fi
> hg init foo
> cd foo
> hg debugbuilddag "$3"
> hg clone . a $1 --quiet
> hg clone . b $2 --quiet
> echo
> echo "% -- a -> b tree"
> hg -R a debugdiscovery b --verbose --old
> echo
> echo "% -- a -> b set"
> hg -R a debugdiscovery b --verbose --debug --config progress.debug=true
> echo
> echo "% -- a -> b set (tip only)"
> hg -R a debugdiscovery b --verbose --debug --config progress.debug=true --rev tip
> echo
> echo "% -- b -> a tree"
> hg -R b debugdiscovery a --verbose --old
> echo
> echo "% -- b -> a set"
> hg -R b debugdiscovery a --verbose --debug --config progress.debug=true
> echo
> echo "% -- b -> a set (tip only)"
> hg -R b debugdiscovery a --verbose --debug --config progress.debug=true --rev tip
> cd ..
