Subject: Preventing merges from one branch into others
Message-ID: <20130207131440.716c1022@bigbox.christie.dr>

[tried IRC to no avail]
I've been trying to find a way to prevent myself from merging a
client-specific branch back into my dev/master branches.  Is there an
easy/straightforward way to do this (perhaps via a hook)?  I didn't
see any sort of "pre-merge" hook script.  Visualized:

  A -> B -> C [dev]
   \
    -> Q -> R -> S [customer-specific]

and I want to ensure that changes Q/R/S never find their way back
into dev.

So I was hoping some sort of "hey, you're an idiot for trying to merge
$CUSTOMER_BRANCH back into dev/master" warning. :-)
