Comment # 1 on bug 1176100 from Sean O'Connell

Clarification: 'pass' fails to find system extensions in *ALL* use cases if
user-defined ENV vars are not set to compensate for the path issue. In my
previous testing, I had set some vars working through the issue and had
forgotten about that. So 'pass otp' appeared to work in some cases, not work in
others. In a clean shell, 'pass otp' was demonstrated to not work at all due to
the lib path issue. As noted previously, adding a symlink to
/usr/libexec/password-store provides a workaround until such time as the
password-store package can be patched.
