Problem with visiting nonexistent .gpg file
reported by Herbert J Skuhra.
* lisp/epa-file.el (epa-file--find-file-not-found-function):
(epa-file-insert-file-contents, epa-file-write-region):
Signal file-missing or file-error instead of epa-error.
This fixes a recently-introduced bug in delete-directory,
where the code assumes the C locale when determining
whether a file-error corresponds to a missing file (Bug#24714).
* doc/lispref/errors.texi (Standard Errors):
* doc/lispref/files.texi (Changing Files):
* etc/NEWS:
Document this.
* doc/lispref/loading.texi (How Programs Do Loading):
Say "a file-error" rather than "the error file-error" since
it might be a file-missing now.
* lisp/emacs-lisp/bytecomp.el (byte-compile-file):
* lisp/epa-file.el (epa-file--find-file-not-found-function):
(epa-file-insert-file-contents, epa-file-write-region):
* lisp/ffap.el (find-file-at-point, dired-at-point):
* lisp/jka-compr.el (jka-compr-insert-file-contents)
(jka-compr-insert-file-contents):
* lisp/net/ange-ftp.el (ange-ftp-barf-if-not-directory)
(ange-ftp-insert-file-contents, ange-ftp-copy-file-internal):
* lisp/progmodes/etags.el (visit-tags-table):
* lisp/url/url-handlers.el (url-copy-file):
* src/fileio.c (report_file_errno):
Signal file-missing if appropriate.
* lisp/epa-file.el (epa-file-insert-file-contents):
* lisp/jka-compr.el (jka-compr-insert-file-contents):
Don't assume file-error is a leaf in the error hierarchy.
* lisp/files.el (files--force):
* lisp/gnus/nnmaildir.el (nnmaildir--enoent-p):
* lisp/jka-compr.el (jka-compr-insert-file-contents):
Use file-missing to detect whether the file is missing.
* lisp/url/url-handlers.el (url-copy-file):
Signal file-already-exists if appropriate.
* src/fileio.c (syms_of_fileio): Define file-missing.

* epa.el (epa-error-buffer): New variable.
(epa-display-error): New function.
(epa-decrypt-file, epa-verify-file, epa-verify-region)
(epa-delete-keys, epa-import-keys): Display output sent to stderr.
(epa-sign-file, epa-sign-region, epa-encrypt-region)
(epa-export-keys, epa-insert-keys): Display output sent to stderr.
Use setf instead of epg-context-set-*.
* epa-file.el (epa-file-insert-file-contents): Use
epa-display-error instead of epa-display-info. Mimic the behavior
of jka-compr when decryption program is not found.
(epa-file-write-region): Use epa-display-error instead of
epa-display-info.
* epg.el (epg-context): Add new slot ERROR-OUTPUT.
(epg-error-output): New buffer-local variable.
(epg--start): Initialize epg-error-output.
(epg--process-filter): Record output lines sent to stderr, in
epg-error-output.
(epg-wait-for-completion): Copy epg-error-output to ERROR-OUTPUT
slot of context.
* epa-file.el (epa-file-insert-file-contents): On error, display
output sent to stderr.
(epa-file-write-region): Likewise.
* epa.el (epa-progress-callback-function): Fix the logic of
displaying progress.
* epa-file.el (epa-file-insert-file-contents): Make progress
display more user-friendly.
(epa-file-write-region): Ditto.
buffer unmodified. (Bug#1509)
* epa-file.el (epa-file-insert-file-contents): Set buffer's
modification time if visiting a file and the content is
successfully decrypted.
