Re: Patch for review

Thanks.  

I've pushed it with all your suggestions included, except that I have
not bothered to replace select with poll.   Personally I find select
easier to understand, although it is a little more verbose.

     According to Google, "interruptible" is the correct spelling (not
     -able).
     
     The code would be a little shorter and easier to read with "poll" in
     place of "select".
     
     It's usually advised to set both ends of the pipe into nonblocking mode
     for a use like this, so that in a corner case where signals arrive
     faster than they can be processed, filling up the pipe buffer in the
     signal handler does not cause the "write" from the signal handler to
     block.  (This is unlikely to happen, but it causes a mysterious hang if
     it does.)
     
     In bash, if I type control+C, then I get a new prompt on a new line.  In
     PSPP, with this patch, I get a new prompt on the same line.  The shell
     behavior seems better to me; it is more familiar, at any rate.
     
     "memcpy (buf, "\n", 1);" seems like a long way to write "*buf = '\n';"
     
     Thanks,
     
     Ben.
