There should be a $platform:tty-name variable

[krader1961]

While working on issue #1263 it occurred to me it would be good if users didn't have to do something like this to write portable code:

use platform
var tty-name
if $platform:is-unix {
    set tty-name = "/dev/tty"
} else if $platform:is-windows {
    set tty-name = "con:"
} else {
    fail "could not determine the tty device name"
}

I thought Go had a constant that defined the appropriate string for each supported platform but I can't find it. Regardless, this seems like something Elvish should provide via a $platform:tty-name variable.

I looked at the Go source code and could not find a single mention of CON:. There are a handle of uses of /dev/tty but no constant that is exposed by the Go stdlib. That surprises me but I still believe adding a platform:tty-name variable will make it easier for a user to write portable Elvish code.

@iandol, Good catch. I had forgotten I had opened this issue when I opened #1633. Closing this as resolved.
