Yeah, it makes sense ; I just had to stumble on it once :)

With my version of git (2.19.1); this works with a local tree (git fetch
/path/to/repo ref) and with a github remote, but not with a gitolite
remote ; I don't think it's safe to assume it'll always work, but it can
work.

Yeah, that's less efficient but that'd fetch all named branches at
least; probably safer than what I tried :)

Anyway, the fix seems to be a hit, so cool!

Thanks!
