main/vim: add support for custom configuration file not managed by apk
Currently the vim-configuration file is hardcoded as
/etc/vim/vimrc. As this file is managed by
apk, I don't really want to make changes to this file. Other distros use a second configuration file which is not managed by a package manager to use for customization, e.g.
Could you please append something like this to the shipped
" Source a global configuration file if available if filereadable("/etc/vim/vimrc.local") source /etc/vim/vimrc.local endif
