- * the next time the user hits carriage return. On Windows platforms,
- * this _can_ be done by reading directly from the console, using
- * getch(). However, this doesn't sit well with programming
- * environments such as Emacs which allow you to create sub-processes
- * running Hugs, and then communicate with the running interpreter
- * through its standard input and output handles. If you use getch()
- * in that setting, you end up trying to read the (unused) console
- * of the editor itself, through which not a lot of characters is
- * bound to come out, since the editor communicates input to Hugs
- * via the standard input handle.
- *
- * To avoid this rather unfortunate situation, we use the Win32
- * console API and re-jig the input properties of the standard
- * input handle before trying to read a character using stdio's
- * getchar().
- *
- * The 'cost' of this solution is that it is Win32 specific and
- * won't work with Windows 3.1 + it is kind of ugly and verbose
- * to have to futz around with the console properties on a
- * per-char basis. Both of these disadvantages aren't in my
- * opinion fatal.
