Support running commands “under” cv

[ortolot]

Hello,

I am highly interested in this software, which I would like to package for Debian as soon as I get some time (which, unfortunately, may only happen in some months…). Anyway, I thought about one possible way of using cv which could be useful:

$ cv COMMAND

For instance:

$ cv cp bigfile /tmp

That would be the same kind of usage than commands like nice for instance, and would imply for cv to fork; in the child, to exec() the command specified in its arguments, and in the parent, to monitor continuously its child.

The shell can already do that when using -p argument. I've just added an example on the README.md page. (& cv -mp $!)

Yes, the shell allows to do that, but it is not exactly equivalent. It
is certainly for shell users, but for scripting or other kind of
integration, it is not. This is good enough for me, but real support for
running a command under cv would be nice to have, so that may be a
future enhancement to keep in mind. But it is by no mean an actual
issue, for sure.
