Causes a nonzero exit status when used in combination with `vipe`

[niklaas]

❯ ls | vipe | xargs echo
nvim exited nonzero, aborting

Closing with :w and then :q works as expected while closing with :wq causes the error.

Line 33 in 287ffdd

call system('cd ' . expand('#' . a:buffer . ':p:h:S') . ' && git rev-parse --is-inside-work-tree --prefix ' . expand('#' . a:buffer . ':h:S'))

is the culprit because it's the last call which updates v:shell_error. When vim is opened using vipe, this isn't within a git repository, so the exit code is nonzero. This will be leaked to vim's exit code.

I haven't found a clever way to prevent this yet since v:shell_error is read only and there's no way to circumvent it.

OK, for the time being, my workaround is not to add the plugin as the last one since that seems not to call the call system mentioned above as the very last one. 😅
