maybe PATCH: 21731 broke handling of prompts with newlines in it

[Stephen Rueger <stephen.rueger@xxxxxxxxxxxxxxx>]

Hello!

Disclaimer: I hardly know any C, and this is my first journey into the
Zsh source that didn't end with me giving up totally swamped, please
treat the following accordingly.

The new multibyte aware promptcount seems to have a test backwards that
checks if the special treatment of \n and \t can be skipped because the
shell is in the middle of processing a multibyte character.

This simple patch should solve the problem:

 			w = (w | 7) + 1;
