evolve: move if-else block under the right block
the index related if-else should be only executed when all three base, divergent
and other have different branch names.
I coded this last night and mistakenly mis-indented it. Caught when I was adding
more tests.
#!/bin/bash
set -euox pipefail
unset GREP_OPTIONS
NOTOPIC="--config experimental.topic-mode=ignore"
compatbranches=`hg branches --quiet | grep 'mercurial-' | grep -v ':' | sort -n --reverse`
prev='stable'
for branch in $compatbranches; do
hg up $branch
hg merge $prev
hg commit -m "test-compat: merge $prev into $branch"
prev=$branch
done
