Subject: [PATCH] branch: improve advice when --recurse-submodules fails

From: "Philippe Blain via GitGitGadget" <[email-masked]>

From: Philippe Blain <[email-masked]>

'git branch --recurse-submodules start from-here' fails if any submodule
present in 'from-here' is not yet cloned (under
submodule.propagateBranches=true). We then give this advice:

   "You may try updating the submodules using 'git checkout from-here && git submodule update --init'"

If 'submodule.recurse' is set, 'git checkout from-here' will also fail since
it will try to recursively checkout the submodules.

Improve the advice by adding '--no-recurse-submodules' to the checkout
command.

    Hi Glen,
    
    This is a small improvement I thought about when looking at that code
    recently.
    
    Cheers,
    
    Philippe.
