Hello,

I just have found a neat way for doing:

:echo system('command')

I attach a small plugin which does the above if the command line starts
with ':! '. If you know of any existing such plugin let me know, if not
I'll be happy to publish it on vim.org. Here are doc notes from the
plugin:

Any suggestions for the plugin name will be welcome.

Best regards,
Marcin
