not working when the branch has a dot character

[Gabriel Soto]

Hello,

I'm calling a basic repreport for a module on my local repo:

<ivy:repreport
    todir="${out.dir}"
    xml="true"
    organisation="${ivy.organisation}"
    module="${ivy.module}"
    branch="${ivy.branch}"/>

Most of the time, the task behaves as expected but every time the branch
contains a '.' it outputs an empty report (the same behavior as if the
branch didn't exist).

Does this limitation make sense?
May I be hitting a bug?
Is it a bad idea to use dots in branch names?

I'm using Ivy 2.4.0.

Thank you!
Gabriel
