mgr update

[David B. Thomas]

For those of you who tuned in late, I've added automatic screen blanking
to mgr.

Just a quick update... Tonight I added an escape code so you can (1) blank
immediately, (2) set the desired blanking interval, in seconds, or
(3) disable the blanking feature.

Some funny things still do happen if a window is resized while invisible...
but it basically works.

Interestingly, I think I may have found a bug (or "feature") in the pty driver.
If you call select with a timeval structure that has a negative timeout
value, it cripples the driver, and it must be deallocated and reinstalled
to work right again.
