The verifications on the different cmd[x] are made in the few lines
"if ... elsif... elsif ... else" right after the split.

We wanted to highlight the fact that we are sending those lines to STDOUT
which is piped into the caller of the remote helper.

Here, we wanted to stick to the convention given by the remote-helper
documentation that indicates the list command should end with a blank line.

As said in previous mails, we are relatively new using perl (it's been
roughly two weeks)
so any advice on how to get things more perl-ish are welcome.

Thanks for your feedback
