I just test like:

1. (setq line-height-factor 1.5)
2. M-x
3. yank "ÄãºÃ"
4. See minibuffer's height change or not.


maybe the height should split two parts, ascent and decent:

   real-ascent = ascent * line-height-factor
   real-decent = decent * line-height-factor

The patch seem to not change decent.
