It could combine the tooltip string lines, and display as much text as
will fit in the echo area. Would that be better?
If this is intentional, the documentation for tooltip-mode should be
changed (as well as the info page on tooltips). With it's current
wording, it sounds like disabling tooltip-mode is the only way to
display help text in the echo area.
I suggest changing the doc to something that mentions tooltip-use-echo-area:
"When this minor mode is enabled, Emacs displays help text in a pop-up
window on mouse-over. When it is disabled, Emacs displays the first
line of help text in the echo area instead.
See `tooltip-use-echo-area' for displaying multi-line help text."
And chage tooltip-use-echo-area to mention this usage:
"Use the echo area instead of tooltip frames for help and GUD tooltips.
Enabling `tooltip-mode' with this is the *only* way to display
multi-line help text in the echo area."
I never would have found tooltip-use-echo-area if Nick had not mentioned it.
