Restricted character set for Github repo names?

Hello all,

This is my first port, I’m trying to port so I may have missed something.

I’ve got my Makefile (copy: ) but on 10.3 it fails with the following:

> _MASTER_SITES_go-md2man= not found
> *** Error code 127

When I tried it on an 11-BETA VM and looked at all errors I got the following:

> + echo 'The MASTER_SITES line has'
> The MASTER_SITES line has
> echo "a group with invalid characters, only use [a-zA-Z0-9_]"
> Execute: 'echo "a group with invalid characters, only use [a-zA-Z0-9_]”'

I then forked the repository to my own Github account and removed the hyphen from the repo name.  Modifying my Makefile (copy: ) it now downloads the repository without an issue.

Is this expected behaviour?  Is it like this for a specific reason?

Kind regards,
