vim-minimal: vi invocation causes filetype.vim error - Issue and Proposed Fix

Hi developers,

When invoking `vi` with the `vim-minimal` package, an error related to
`filetype.vim` occurs, as detailed in this issue report:
https://github.com/vim/vim/issues/17039 (Please note: I only commented
on this issue, I did not open it).

The problem stems from the line `filetype plugin on` in `/etc/virc`,
which is generated from `/etc/defaults/etc/virc` during setup. The
`filetype` plugin requires the `eval` feature, which is currently
disabled in `vim-minimal`.

I believe this `virc` file originates from Fedora, as evidenced by the
inclusion of `fedora/virc` in `vim.cygport`’s `SRC_URI`.

The issue appears to be resolved in the latest Fedora version (see:
https://src.fedoraproject.org/rpms/vim/c/36cadcf4bf451f59b0d06e6cb9aa2b2e3ca7ef54?branch=rawhide
), but this fix hasn't been reflected in the current Cygwin package.

Applying the diff from the linked Fedora commit and re-packaging
`vim-minimal` should resolve the problem.

It would be beneficial to include a note in the package update
documentation. A fresh installation will automatically include the
fix, but existing installations won’t be updated unless the
`/etc/virc` file is manually edited.

Regards,
Yasutaka ATARASHI
