One thing I can't understand is why the text window
is always redrawn completely when the tag line is edited. I'll take a
look
in the future.
AFAIR from when I looked into it, this behavior was introduced in
commit ba7c22f781dafd30d0b97179c941476639022285

Added the p9p acme patch the allows multiline tags (thanks rsc and
lf94).
I think the redraw happens because when you add a character to the tag
you may need to wrap to a new line.
As a stopgap for myself, I've just removed the call to winresize from
winsettag1.
In principle one should be able to figure out the width of the text in
the tag and how many lines are needed, and redraw only if that number
changes after a character is typed, but I wasn't able to figure out
where to do this in the code.
