I do not claim to understand the details either, but at least I can
confirm such behavior change. And maybe I can provide a test case. I was
happy with my vim configuration on several machines (Debian, Ubuntu,
LFS) for years, but some update a couple of months ago started to drive
me nuts every now and then - mouse support was broken for me: Marking
stuff on a console in putty (Windows ssh client) used to end up in the
clipboard automatically, and it still does - unless using vim. I even
switched to using nano temporarily just to make that work again.
Reason was a "mouse=a" in some default pulled in "recently".
Documentation suggests this is something everybody would want to make a
mouse work, but I certainly do not, because it makes vim "capture" the
mouse internally which breaks my usage of it.
Anyway, the problem is not that "mouse=a" was there, but how to disable
it again. There is "mouse=" in the book which did not seem to help.
"mouse-=a" suggested somewhere did not either. I ended up commenting out
every occurence of that setting in any vim file on the respective system
to get rid of that. This is not an *LFS issue but a vim configuration
issue on multiple distributions.
I'd prefer to understand the correct (current) order of (overriding) vim
configuration, though...
We tried to fix this, but perhaps didn't do it well enough. We added:
source $VIMRUNTIME/defaults.vim
let skip_defaults_vim=1
I suspect removing or commenting out the source command will do what
most of us want.
The first part of defaults.vim has:
if exists('skip_defaults_vim')
finish
endif
What we had was trying to prevent defaults.vim running twice. I think it
was automatically run if ~/.vimrc did not exist.
The offending command in defaults.vim with regard to the mouse is
mouse=a
Setting mouse=r later in the initialization fixes things, but if set in
/etc/vimrc and defaults.vim runs after that because ~/.vimrc dies not
exist, then the mouse setting is changed back.
