Robert Watson 09333c6166 o nvi failed to correctly handle EINTR returned from tcsetattr(), exiting ... instead of recovering, which happens in particular during a rapid series of SIGWINCH's. This change forces nvi to loop on the call in the event that the call is interrupted. Interestingly, I submitted this bug report in 1998, and a solution was posted shortly thereafter by Matthias Buelow; it's been sitting in the PR database ever since. Note: this takes this file off the vendor branch. If and when we find a vendor for this code, the fix should be given back to them.
