Hi.
When tooltip-mode is disabled or more general when show-help-funtion
is nil the help messages are shown in the echo area. During display
message-truncate-display is bound to t. I suspect this was done to
avoid a "jumping echo area". This is nice but i would accept this
tradeoff to see the whole help message.
This patch adds a variable show-help-echo-truncate that can be used to
control this behavior. It is bound to t to be compatible with the
current code.
If needed i could write News or ChangeLog entries too..
Thanks,
Stephan
