juju scp reports -r as an invalid option

[Brad Crittenden]

The help for 1.19.2 'juju scp' shows an example using the '-r' option as seen here:

% juju help scp
usage: juju scp [options] <file1> ... <file2> [scp-option...]
purpose: launch a scp command to copy files to/from remote machine(s)

[...]

Recursively copy the directory /var/log/mongodb/ on the first mongodb
server to the local directory remote-logs:

    juju scp -r mongodb/0:/var/log/mongodb/ remote-logs/

However when trying to do a recursive copy I get an error.

juju scp -r ~/charms/precise charmworld/0:/tmp
error: flag provided but not defined: -r

The help text should not describe options that are not supported. So the help needs to be fixed or the -r should work. The latter would sure be the nicer of the two outcomes.

% juju --version
1.19.2-trusty-amd64

As a work-around, this spelling is rumored to work:

juju scp -- -r $source $target

This bug is duplicate of https://bugs.launchpad.net/juju-core/+bug/1214642

The workaround @bac mentions actually works.

I tested the devel (alpha) version (1.21-alpha1-trusty-amd64, from devel ppa), and the bug is still there.

However, some time ago I built, from sources (1.20.9-qiana-amd64 - was trying to make juju work on Mint), and the bug is not present there (in a manner that the help message is fixed)
