It's been a year or so since my last complaint, time to complain again!
wcmd is currently unusable when DISPLAY is not set.
Normally, you can do programs/wcmd/wcmd and get a nice DOS prompt. However, if you do unset DISPLAY programs/wcmd/wcmd you get a nonfunctional DOS prompt; for each keystroke, it gives you a new prompt. Pressing ^C terminates wine, and leaves stdin in raw mode. This makes it really friggin' hard to use batch files in a cron job or any other situation where you don't have X available. (And *please* don't tell me to set up a fake X server for this; that should simply not be needed. )
I get pissed off about this every time I run into it, and I'm getting tired of having to figure this out over and over again. Grr, grr, grr. Maybe I should figure out how to make a regression test for this so the next time somebody breaks it, I'm not the first person to notice.
