Do you need some sort of configuration in ~/.ssh/config?

Is the `+' character in the `Host' entry in ~/.ssh/config?

I'd like to reproduce the problem you are describing, but I need more
information on how to do it.

As mentioned by Ville Skyttä in his reply [1], this should be fixed
upstream, as a side-effect of a refactoring. However, the patch has
been committed after the release of version 2.8.
I can certainly backport it to Debian (and I have already done so in a
local branch), but it would be nice to reproduce the bug and check that
the backport actually fixes it.
So, could you provide some `steps to reproduce'?
Thanks,
Gabriel
