bug#61190: 28.2; ispell personal dictionary location for hunspell engine

[O G <opngid@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 6005 bytes --]

The ispell package in Emacs is not using the user-specified location of
the personal dictionary for hunspell.

In particular, neither of these two settings are being respected:

(setq ispell-personal-directory "/c/Users/xxxx/.hunspell_en_US")
(setq ispell-cmd-args "-p /c/Users/xxxx/.hunspell_en_US")

Instead, it appears that ispell is hardwired to use the file
%USERPROFILE%hunspell_en_US regardless of whether or not the user has
specified another choice for their personal dictionary.

Note that a file named %USERPROFILE%hunspell_en_US is being created at
the save prompt when adding a new spelling regardless of whether or not
a file named .hunspell_en_US already exists in the user's home directory
(the default file path for a personal directory) and that the Windows
macro %USERPROFILE% is not being properly expanded either (so it becomes
part of the dictionary name in unexpanded form).

Hunspell is the latest version (1.7.2) installed from the MINGW64 repository
in the MYSYS2 project.  It is otherwise working just fine with Emacs
using the following two settings:

(setq ispell-program-name "hunspell")
(setq ispell-local-dictionary "en_US")

Note that the HOME variable is set in my Emacs init file and points
to C:/Users/xxxx/

A comment in this stack exchange post suggests others may be
experiencing this issue as well:
