bug#47456: 27.1; emacs hangs using aspell in auctex

[Brian Elmegaard]

I am not sure where the mistake is. I include a few comments below.

*Aspell*
It gives:
>\msys64\mingw64\bin\aspell -vv
@(#) International Ispell Version 3.1.20 (but really Aspell 0.60.7)

*Hunspell 1.3*
For hunspell I was able to use the version on sourceforge 
https://sourceforge.net/projects/hunspell/ without any customization.
But it seems not to be updated:
hunspell.exe -v
@(#) International Ispell Version 3.2.06 (but really Hunspell 1.3.2)

*MSYS Hunspell 1.7*
For the msys hunspell
\msys64\mingw64\bin\hunspell.exe -v
@(#) International Ispell Version 3.2.06 (but really Hunspell 1.7.0)

It also runs fine from a command line using:
\msys64\mingw64\bin\hunspell.exe -d en_US -a file.tex

But in emacs, this did not work. Neither with ispell-buffer, nor with the same 
command line in eshell.

I could only get it to run if I set DICTIONARY in .emacs:
(setenv  "DICTIONARY"  "en_US")

Other ways using DICPATH, ispell-local-dictionary-alist, ispell-extra-args, 
ispell-dictionary, ispell-local-dictionary did not make it work.

Thanks.

Could it be that a recent Aspell release deprecated the "+" command?
If you tell me the version of Aspell you have, I can check.  Try invoking 
Aspell from the shell prompt like this:

  aspell -vv

then tell what this produces.
