--help was the first thing I tried which worked. using --version is
better of course - but who cares?
My code only does the check if vim is used - and falls back to gvim
assuming that most people installing it also have client-server.
For my case its reasonable.
I just feared about me or my system being insane when I saw that
system('gvim --help') yielded an empty string.
Maybe --(help|version) should onnly write to stdout and additionaly
--(help,version)-gui could be added only if somebody is found having a
use case for it? People knowing about --help usually also know how to
redirect.
Current behaviour doesn't follow the principle of least surprise which I
like much. That's why it might be worth changing - but its neither
urgent nor very important to me.
