Ummm, how about:
For most commands, '--changelist FOO' restricts the scope to items
in the intersection of changelist FOO and the specified (or default)
depth. But for *some* commands, certain special commands, commands
with trust funds and their own ponies and idyllic summer vacations,
'--changelist FOO' changes their non-infinity default depth to
infinity, so that the changelist becomes the only restriction when
no depth restriction is explicitly given.
Then we just have to decide which commands are special in this way,
'info' being an obvious candidate. Are there any others; maybe
I know people will cry "inconsistency", but I'm not sure consistency
is a major factor in good UI anyway. Meeting intuitive expectations
is more important.
