For the same reason as cdc0cc3601. This will help notice problems like wrong
target revision.
The warning for multiple branches is reorganized as a hint for "-r" option,
which I think is the main purpose of this warning. Unlike "squash", we don't
check if an argument can be parsed as a revset because branch name is usually
a valid symbol expression.
