[gentoo-science] [patch] system-wide install of debug_gap.vim can not be overridden

[P Purkayastha]

Hi,

   I installed sage and also gap via the sage-for-gentoo overlay on a 
Gentoo linux system (64 bit installation). It turned out that gap 
installed a plugin /usr/share/vim/vimfiles/plugin/gap_debug.vim where 
some keybindings are defined to help debug gap programs.

First, I think this file should go under 
/usr/share/vim/vimfiles/ftplugin directory since it applies only to gap 
files. Secondly, the files define some keybindings without allowing for 
the user to override those keybindings in ~/.vimrc.

I am attaching a patch which defines a global vim variable. If the user 
sets that variable in ~/.vimrc, then this gap plugin will not be read. 
This is one way I think the plugin can be made to not supersede user 
settings.

If there is some other way of overriding that plugin file, please let me 
know.

    Thanks and regards,
      Punarbasu.
