The infloop has been observed in calls to `pasword-store--run'
for pass v1.7.4 in a Windows/WSL2 enviroment.

When this happens, the sentinel in `password-store--run-1'
doesn't call the callback.

* contrib/emacs/password-store.el (password-store--run-1):
Prefer `process-status' over the string comparison to check the
process status.

The "f" library is a rather thin translation layer for already
existing Emacs functions.  Most functions directly map to an already
existing function (eg. "f-no-ext" and "file-name-sans-extension").  For
this reason, removing "f" comes at no cost while reducing the number
of dependencies one has to count on and the user has to install.

Clarify that the optional argument is only used in the `message' call.
Bump version to v2.1.3.
* contrib/emacs/password-store.el (password-store-clear): Update docstring.
* contrib/emacs/CHANGELOG.md: Document this change.

This change preserves backward compatibility with previous
version of the function.
Bump version to v2.1.2.

* contrib/emacs/password-store.el (password-store-clear):
Make argument FIELD optional.

* contrib/emacs/CHANGELOG.md: Announce this change.

For auth-source-pass versions < 5.0.0, auth-source-pass-filename
is not defined; thus, we must check that this variable exists before
use it.

* contrib/emacs/password-store.el (password-store-dir): Call
bound-and-true-p on auth-source-pass-filename.

Allow users to retrieve any secret field stored in the files.
Use auth-source-pass to retrieve the secret fields.
Bump version to v2.1.0.

* contrib/emacs/Cask: Replace dependency on `s' library
with auth-source-pass dependency.

* contrib/emacs/password-store.el
(password-store-url-field): New option.
(password-store-dir): Use `auth-source-pass-filename'.
(password-store-read-field, password-store-get-field)
(password-store-copy-field, password-store-parse-entry): New functions.
(password-store-read-field): Use password-store-parse-entry.
(password-store--save-field-in-kill-ring): New function extracted from
`password-store-get'.
(password-store-url): Use `password-store-get-field' and
`password-store-url-field'.

* contrib/emacs/README.md: Update documentation.

* contrib/emacs/CHANGELOG.md: Announce changes.

Before, the following message was shown:
"Enter contents of ENTRY and press Ctrl+D when finished:\n\n"

Since the command is not interactive, it is better to show users
specific messages on success/failure.

* contrib/emacs/password-store.el (password-store-insert):
Improve message shown on success/failure.

Some libraries rely on this function, e.g. password-store-otp library.

* contrib/emacs/password-store.el (password-store-timeout):
Re include this function; now it just returns
password-store-time-before-clipboard-restore.

Using a customizable variable is the preferred way to set
a parameter within Emacs;  replace password-store-timeout with
the new option password-store-time-before-clipboard-restore.

The default value for this variable uses the environment var
PASSWORD_STORE_CLIP_TIME when set; this is the same behavior
as before.

Add Maintainer header.
* contrib/emacs/password-store.el (password-store-password-length):
Increased default value from 8 to 25, i.e. same default as
in the shell script.

(password-store-time-before-clipboard-restore): New option.
(password-store-timeout): Delete it.
Use the new option instead; all callers updated.

* contrib/emacs/CHANGELOG.md: Announce the features.
