bzr diff -r1 -r2 does not give error or expected result

[Deepinthekernel]

Giving bzr diff two -r options seems to result in silently ignoring the first option.

bzr diff -r1..2

gives the expected result

bzr diff -r1
bzr diff -r2

both give the expected result of diffing with the current working files.

bzr diff -r1 -r2

ignores the first -r argument.

This is particularly confusing as legal cvs usage would be to give cvs diff two -r options - bzr should at least complain if two options are given even if it cant do the default cvs-type thing.

It makes no matter if the options are given as -r 1 , -r1 or -r revno:1
