Subject: type-break-keystroke-threshold: Change default wpm to 30 and lower
X-Git-Tag: emacs-19.34~7571
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=f486195cb1d38aeef29c4d63f0f2aa8cf6730cd5;p=emacs.git

type-break-keystroke-threshold: Change default wpm to 30 and lower
threshold to 1/5, rather than 1/4, of upper.
type-break-guestimate-keystroke-threshold: Change threshold fraction here too.

type-break-demo-life: Restart when all life perishes.
