My apologies for the cut-and-paste here. I had "digest enabled".

OK - well maybe I need to put that on my backlog. It just one code-path
for Windows and another for POSIX. Just a few lines of code for each.

So I couldn't find an active issue tracker on the repos in Github. I
tried to create a Trac issue, but it rejected my ticket for having external

account. I do not. Is trac the primary issue-tracker?
