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.

Bakul Shah has observed corrupted files being written
when acme writes over osxfuse to sshfs to a remote file system.
In one example we examined, acme is writing an 0xf03-byte
file in two system calls, first an 0x806-byte write and then a 0x6fd-byte
write. (0x806 is BUFSIZE/sizeof(Rune); this file has no multibyte UTF-8.)
What actually ends up happening is that an 0x806-byte file is written:
0x000-0x6fd contains what should be 0x806-0xf03
0x6fd-0x7fa contains zeros
0x7fa-0x806 contains what should be 0x7fa-0x806 (correct!)
The theory is that fuse or sshfs or perhaps the remote file server is
mishandling the unaligned writes. acme does not seem to be at fault.
Using bio here will make the writes align to 8K boundaries,
avoiding the bugs in whatever underlying piece is broken.

Introduces the Search command for mailboxes.
Arguments passed are treated as one space-
separated string, passed on to mailfs' IMAP
search interface.

Mail services (such as Google Mail) will often have
directories with names that contain spaces. Acme
does not support spaces in window names. So, replace
spaces in mail directory names with the Unicode
character for visible space.
The code is a bit of an over-approximation and
generally non-optimal.

UTF-8 searches with the SEARCH command must
be conducted in two steps: the first sends
the SEARCH command with the length of the
UTF-8 encoded string and the second sends
the literal search term. The searches need
to not be quoted.

Everyone seems to assume that TERM != dumb implies
ANSI escape codes are okay. In fact, many people assume
that unconditionally, but it is easier to argue back about
TERM=dumb than TERM=9term.
This applies to acme win too, because they share the code.
Set termprog=9term or termprog=win for clients who
need to know.

There are two bugs in pdec() on INT_MIN:
* wrong output.
`n = 1-n' should be `n = -1-n' when n is INT_MIN.
* infinite loop.
gcc optimizes `if(n>=0)' into `if(true)' because `-INT_MIN' (signed integer overflow) is undefined behavior in C, and gcc assumes the negation of a negative number must be positive. The resulting binary keeps printing '-' forever given INT_MIN.
Try the simplified pdec.c below.
$ gcc pdec.c
$ ./a.out -2147483648
--214748364*
$ gcc pdec.c -O2
$ ./a.out -2147483648
<infinite loop>
$ gcc pdec.c -O2 -D__PATCH__
$ ./a.out -2147483648
-2147483648
=== pdec.c ===
#include <stdio.h>
#include <stdlib.h>
#include <limits.h>
#define io void
void pchr(io *f, int c)
{
putchar(c);
}
void pdec(io *f, int n)
{
if(n<0){
#ifndef __PATCH__
n=-n;
if(n>=0){
pchr(f, '-');
pdec(f, n);
return;
}
/* n is two's complement minimum integer */
n = 1-n;
#else
if(n!=INT_MIN){
pchr(f, '-');
pdec(f, -n);
return;
}
/* n is two's complement minimum integer */
n = -(INT_MIN+1);
#endif
pchr(f, '-');
pdec(f, n/10);
pchr(f, n%10+'1');
return;
}
if(n>9)
pdec(f, n/10);
pchr(f, n%10+'0');
}
int main(int argc, char **argv)
{
int n = atoi(argv[1]);
pdec(NULL, n);
putchar('\n');
}

Ubuntu Precise seems to have a buggy X server
that sometimes fails at XCopyArea. Let devdraw
do it itself.
This will slow down remote X a little bit,
but slow and correct is better than fast and broken.
