pinentry 0.9.5 added a pinentry-emacs program and an "INSIDE_EMACS" fallback
mode, but those features and mechanisms do not appear to be documented anywhere
in doc/pinentry.texi (or anywhere in doc).
When i try to run pinentry-emacs manually to test it out (even from within M-x
shell), i get a terse and inexplicable failure:
0 $ ./emacs/pinentry-emacs
stat: No such file or directory
There is also no indication in the documentation of what i need to do to my
emacs installation to make sure that it works correctly.
Given the lack of documentation, the opaque failure modes, and the vague concern
about abuse of INSIDE_EMACS from non-emacs environments i've currently disabled
those features in the pinentry 0.9.5-2 upload to debian.
If the documentation and failure modes are clarified, i'm happy to re-enable
them in debian, and potentially to add a new pinentry-emacs package if there's
reason to think that would be desirable.
