It can't! How would it? Nobody has ever stated that addslashes() can
undo a stripslashes() call. That's like expecting there to be an untrim()
call to match trim(), for example.

Not quite, stripslashes() understands the sybase style of escaping ('')
and it is faster than strtr for that case.

Correct. The goal of stripslashes() was simply to get rid of the set of
slashes added by magic_quotes for display purposes and it achieves this
quite nicely.

And it does. But the manual doesn't say that it *only* removes slashes
added by addslashes.
