I think the major reason why people prepend `silent` to `!` commands is
to avoid the "Press Enter to continue" prompt, as recommended in the
help:
Vim redraws the screen after the command is finished,
because it may have printed any text. This requires a
hit-enter prompt, so that you can read any messages.
To avoid this use: >
:silent !{cmd}
But now that I think of it, if I want to avoid affecting the screen at
all, it would be more appropriate to use `call system(…)`. Perhaps this
deserves a mention in this section of the documentation?
