Sorry hiro, I mean that I imported the acme version of 9front to
my system (based on 9legacy) because it has been updated along the
plan9port repo. But there are more fixes and improvements that
could be imported (to 9front's acme) from plan9port. This patch
makes 9front's acme able to open files and dirs with spaces in
their names. 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.
Anyway, I remember seeing a version of plan9port with the apps from
9front somewhere, I'm surprised you didn't know about it.
adr.

aaaah, sorry for missing the other direction :D

yeah, i heard about that one, it's a bit surprising that's still not fixed.
but many people use just sam on 9front and never notice such things.
my memory of acme is fading :)

yeah in fact i wanted to make sure you don't use that one, bec. really
it never got much care and 9fans/p9p was always it's upstream.
otherwise, i guess there's also the inferno version of acme (i am a
former acme-sac user).

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.
