Increase version or a prerelease

[javierpavon2000]

I have configured the releaseName as 'rc', like
prereleaseName: 'rc'

if my current version is 0.3.24 and I perform
grunt bump:prepatch
the new version is 0.3.25-rc.0, that's ok

The problem comes when I want to bump to the next rc, rc.1.
If i perform
grun bump:prepatch
over 0.3.25-rc.0, I expect to have 0.3.25-rc.1, but I have 0.3.26-rc.0

It's a bug or I have to config something?
Thanks

PD: I'm using last version 0.8.0

Looks like a bug to me, too.
