compatability options for CVS refugees

[James Troup]

I consistently try to use CVS command line options with bzr and often fail. When these options/arguments are not already in use for something else, it might be nice to support them to help CVS refugees like me.

The ones I use a lot are:

 (o) -u option to diff (this would obviously be a no-op in bzr)
 (o) -r <n> -r <n+1> (instead of -r <n>..<n+1> or whatever the correct bzr-ese is)

[John A Meinel (jameinel)]

We could add -u for diff, though I'm not positive of the benefit. I suppose when fingers are hard-wired it could be nice.

-r X -r Y is a lot more difficult to support (I'm not sure about our current parser, but the older parser wouldn't allow you to give the same option twice, I think the new one always picks the last supplied).

Which honestly I use, because I have an alias of "log = log -r -10..-1" which is really nice for just previewing what has changed recently. But I do need to override it with 'bzr log -r -40..-1' sometimes.

It is marked as a wishlist, though something like this might be a great place for a plugin. Which could enable 'cvs compatibility mode' or somesuch.

optparse supports this natively, so it's just a matter of hooking into
that support, if we choose to do this.

What's interesting is that such a plugin would just need to replace the
definition for 'revision' in options.py
