.		<- Raid, kills bugs

	Okay, would any vi hacks out there like to explain the following
to me.

1.	Why is the 'Y' command destroyed by mapping the character
	'_' (underscore 0x5f) to any command sequence?  This destruction
	is reversed by unmapping that character.

2.	Why is the ":cd" command documented only in the source?

3.	Why does the undocumented command '~' (tilde 0x7e) not accept an
	repeat count?

4.	Why does using the 'R' command to replace text, when the replacement
	continues past column 80 (and wraps), semi-trash the next line?
	By semi-trash, I mean that causing vi to redisplay those characters
	will cause it to display the wrong characters, until a '^L'
	(form feed 0x0c), 'z' or other screen re-drawing command is done.

Thank you for your time.
