Ouch, Myke.  I just realized that this is wrong.

You can't use "movf STATUS, W" because it can (and will) change the Zero bit
and affect the initial STATUS value.  To move it into a temp location
without affecting the original STATUS register, you have to use "swapf
STATUS, W" and "movwf status_temp".  Then to restore it, you just "swapf
status_temp, W" and then use "movwf STATUS".
