EXIT STATUS section, mention the full command rather than only the sub command.

When printing the doc for the exit code statuses the following is used:

`P "$(tname) exits with the following status:"
31

There are two issues here:

1. status should be statuses since there is more than one exit code in most cases.
2. The full command name is not printed, but rather the subcommand. For instance

  EXIT STATUS
         rpc exits with the following status:

should rather be

  EXIT STATUS
         dune rpc exits with the following status:

1. status should be statuses since there is more than one exit code in most cases.

I disagree, using statuses would convey that it is possible to exit with more than one status. You should read the preamble sentence and each case as a declaration.

[Alizter]

Then perhaps it should be:

         rpc exits with one of the following statuses:

[dbuenzli]

But then you need to deal with singular and plural.

[Alizter]

Is it likely that it is ever singular however? That seems to be an edge case here.

[dbuenzli]

Well you won't be the person who gets an issue the day a user of the library falls on the case and decides to report it…

Regarding 1. I simplified the default EXIT STATUS wording to $(iname) exits with: which works with both singular and plural.

Thanks!
