The editor included sbfs.asm and console.asm, which was 3235 of its 4941
bytes. Both come out: reading and writing a file, printing and reading a
line are services now, and sbfsMount goes entirely because the system has
already mounted the disk. Only text.asm remains, at 357 bytes, because
textSame and textNumber own nothing and touch no device - sharing those is
a linker's job rather than an operating system's.
4941 bytes to 1983, a little better than predicted because dropping the
mount and the blocks-and-tail arithmetic went with the library rather than
being translated.
ConsoleEndOfInput went with console.asm, so the end of input is now read
from the console status port. That is better than what it replaced: the
port is there whether or not the system is.
Nothing it does changed, and that is checked rather than asserted. The
recorded output of the cosmosEdit test does not move by a single byte
across this commit - a test written days before the rewrite, checking a
property rather than an output, and therefore able to verify a change it
knew nothing about.
One thing is lost and worth naming: there is no way to ask whether a disk
is present, so the editor's "there is no disk" message is gone. On a
diskless machine it now opens an empty document and fails at w instead. The
shell already refuses to load without a disk, so the editor cannot normally
be reached that way.
