Invalid output when using range tags

This is from running changelog on https://github.com/lerna/lerna

lerna-changelog --tag-from v2.0.0-beta.32 --tag-to v2.0.0-beta.34

What exactly am I looking at here? Can you point out the issues you see? Thanks 😉

[hzoo]

So I think I would expect the changelog to have 3 entries?

first issue is the first entry is v2.0.0-beta.3 (2017-01-26) - missing a 2?

Also I'd think the order would be 32, 33, 34 or 34,33,32

and lastly the commits don't seem to correspond to the commits in the repo?

I'll have a look into it as soon as I have some time.

@hzoo the problem is that we are using indexOf() to figure out what tag a commit belongs too and v7.0.0-beta.1 is obviously matching v7.0.0-beta.10 too 😉
