Patched in the f33 branch 3 years ago.

Or upgrading the fedora submodule vim repo to f33-f42/main/rawhide branches to 
pick up the updated virc, or downloaded from

	https://src.fedoraproject.org/rpms/vim/raw/f33/f/virc

Package vim-minimal should have the parts of vim-common postinstall and 
preremove vim.sh scripts dealing with virc (which is not packaged in vim-common) 
moved into its own vim-minimal postinstall and preremove scripts.

These vim.sh scripts install virc (and vimrc) from defaults if each does not 
exist and remove installed virc (and vimrc) if each has not changed from that 
installed from defaults.
