Hi Dwayne,

        I just hacked this together and committed it to CVS, but what do
you think:

#ifndef NANO_SMALL
int open_pipe(char *command)
{
    int fd[2], pid;
  
  /* Make our pipes. */

    if (pipe(fd) == -1) {
        statusbar("Could not pipe");
        return 1;
    }

    /* Fork a child */

    if ((pid = fork()) == 0) {
        close(fd[0]);
        dup2(fd[1], fileno(stdout));
        dup2(fd[1], fileno(stderr));
        /* If execl() returns at all, there was an error. */
      
        execl("/bin/sh","/bin/sh","-c",command,0);
        exit(0);
    }
    else if (pid == -1) {
        statusbar(_("Could not fork"));
        return 1;
    }

    /* Else continue as parent */
    close(fd[1]);
    read_file(fd[0],"stdin",0);
    set_modified();
    return 0;
}
#endif /* NANO_SMALL */
