$teaser misnamed in themes (theme_node)

The documentation to theme_node clearly says the the parameter $teaser is "Whether to display the teaser only, as on the main page." Naming this parameter $main in the themes is confusing. Main is used elsewhere to mean "whether to show full view or teaser view", but the meaning of $teaser seems to be subtly different.

An alternate to the patch I'm suggesting would be to eliminate $teaser altogether, system-wide. The variable $main makes it clear that it is transmitting state (whether or not on the node's main page), whereas the variable $teaser makes on think it is transmitting the actual teaser.
