[development] Create a node revision programatically

[Eric Schaefer]

Hi List,

I want to create a new revision of a node from a module. I could not
find a function for that in the api docs (D6). I figured out (by
poking at node.module) I could just set $node->revision to TRUE and
set $node->log to something meaningful and it works. But since I did
not find any documentation about this I thought I should ask here
before breaking anything. Is my approach correct or will it do
something "surprising"?

Regards,
Eric
