I need to edit some files that decrypt properly with gpg 1.4 but not gpg
2.1. I have both installed on my system, with 1.4 as /usr/bin/gpg1 and
2.1 as /usr/bin/gpg2. The bug is that emacs ignores the epg-gpg-program
variable *except* in error messages, which is very confusing. To
reproduce this problem, do the following:
* Run strace -o /tmp/log emacs -Q
* Eval expression (setq epg-gpg-program "/usr/bin/gpg1")
* Open a gpg-encrypted file
By examining /tmp/log, or running ps, you can see that emacs is
executing a command like the following:
/usr/bin/gpg2 --no-tty --status-fd 1 --yes --enable-progress-filter --command-fd 0 --output /tmp/epg-output6602ygi --decrypt -- /tmp/x.gpg
However, when it fails to decrypt, it prints the message: Error while
decrypting with "/usr/bin/gpg1." This is obviously very frustrating
since gpg1 can in fact decrypt the file. Ideally emacs should obey
epg-gpg-program, but if it doesn't, it should properly report what
failed.

I have a similar problem with epg-gpg-program. See bug#24229
(https://debbugs.gnu.org/cgi/bugreport.cgi?bug=24229) for some
discussion that might be relevant.

And I want to close this as a duplicate of that bug. Is there still
anything we can technically do for this? Isn't it enough to suggest:
M-: (custom-set-variables '(epg-gpg-program "gpg1" t))
instead of setq?

Respectfully, the usability bug here is different: EPA/EPG only uses the
customized value, while the log message only uses the actual value in
the variable. So the log messages should be adjusted, if you want to
keep using the customized value only in EPA/EPG. And perhaps they should
catch and mention the case where the customized value is not the same as
the variable value, again for usability's sake.
