bug#60966: 30.0.50; Emacs -nw on msys2 is not clearing the terminal

[Ergus]

Hi Eli:

1)

I think you can close this issue or just add a comment about it
somewhere in the documentation...

So, it is done from my side. (If I get some time I will try to fix the
build system script, but not now)

2)

I have another issue because rgrep + MS-Windows does not work for me, I
try to use it like usual, but I get this:

FIND: Parameter format not correct

Grep exited abnormally with code 2 at Tue Jan 31 17:25:49

------------------------

I tried this simplified version of the command from the msys-mingw64
terminal and it actually does not work.

find -H . -type d "(" -path "*/.git" ")" -prune -o type -f "(" -iname "*" ")" -exec grep -e 
"protoc" "{}" ";"

Is this a known issue for you? Else, I can open a new issue if you
prefer.

3) Is it there a clean way I could migrate one emacs installation
(packages in the elpa directory) between machines? Because the machine I
am using now does not have access to internet from the terminal (the
system has some ldap proxy); so, emacs cannot access elpa/melpa or
github to download any package.

Is there some tool in emacs intended for this purpose?

Thanks in advance,
And sorry for the bother
Ergus
