Bad remote file systems can change mtime unexpectedly,
and then there is the problem that git rebase and similar
operations like to change the files and then change them back,
modifying the mtimes but not the content.
Avoid spurious Put errors on both of those by checking file
content.
(False positive "modified since last read" make the real ones
difficult to notice.)
Reading /mnt/acme/log reports a log of window create,
put, and delete events, as they happen. It blocks until the
next event is available.
Example log output:
8 new /Users/rsc/foo.go
8 put /Users/rsc/foo.go
8 del /Users/rsc/foo.go
This lets acme-aware programs react to file writes, for example
compiling code, running a test, or updating an import block.

If the mouse was in the tag of the old window,
it was most likely pointing at Del. If bringing up a
new window from below and not moving the mouse
somewhere else, adjust it so that it ends up pointing
at Del in the replacement window's tag too.
This makes it easy to Del a sequence of windows in
a column, from top to bottom.

Home and End previously navigated between
two different window locations: the top and
the bottom of the text. Now they include a
third waypoint: the location where typing last
happened. Thus, in a win window, typing
ls -l
<home>
scrolls to the beginning of the ls -l output.
A second <home> continues to the top of the file.
Makes Send scroll always, along with writes by
external programs to +Errors.

Ignore scroll/noscroll window setting.
Instead, scroll when the write begins in
or immediately after the displayed window content.
In the new scrolling discipline, executing
"Noscroll" is replaced by typing Page Up or
using the mouse to scroll higher in the buffer,
and executing "Scroll" is replaced by typing End
or using the mouse to scroll to the bottom of
the buffer.

Move libfmt, libutf into subdirectories of lib9.
Add poll-based socket i/o to libthread, so that we can
avoid using multiple procs when possible, thus removing
dependence on crappy pthreads implementations.
Convert samterm, acme to the single-proc libthread.
Bring libcomplete, acme up-to-date w.r.t. Plan 9 distribution.
