If I had to guess, it's probably the same as the problems I was seeing
with gpg-agent not being able to capture the tty correctly to prompt for
the password.  I never had a problem with the ssh agent though.

Unfortunately I do not have a good solution for it, as it seems to
happen only to some people some time on some systems.  After fighting
with it for an afternoon, I simply wrote a pinentry program with my
password hardcoded into it.  Yay for security.

The hack is here for reference (DO NOT USE ON PUBLIC PRODUCTION
MACHINES!) -> https://x.cygwin.com/ml/cygwin/2019-01/msg00178.html

I recheck the stock program every few months, and this problem still exists.
