Treatment of "your" and "my" undocumented #11
Description
Inform has some built-in behavior around the word your in the source text that doesn't seem to be documented anywhere. It sets the object to be proper-named, printed name to include "your", and indefinite article to be none. All of this would be expected if it didn't treat "your" specially, but then it understands "my" for the object and not "your". There is also some undocumented special behavior around "my" in the parser and it's not clear how that affects it.
