ajax beat you to neomagic:

glint seems to have been a false match in my grep - I hit the call to

You can't assume that - just that few people run directly from git on
lesser used hardware.   Most developers running from git do so on
widely used desktop or laptop hardware, not old machines or rackmount

I know we have -ast users, since that's the remote console in a number
of current Sun servers (both SPARC & x64) - but they get stable builds
shipped, not git head.

Neomagic was the source of the two bugs I saw, so it has some users.

I expect -rendition is entirely unused since it's ancient.   (Last time
I looked for info on it, I found that Windows 98 dropped the driver for
it, since it was obsolete even then.)  glint I don't know.
