quick fix to hush.c

[Robert P. J. Day]

  i just committed the following cheap and easy fix to hush.c:

==================================
--- hush.c      (revision 15716)
+++ hush.c      (working copy)
@@ -1284,7 +1284,7 @@
        int i;
        int nextin, nextout;
        int pipefds[2];                         /* pipefds[0] is for reading */
-       struct child_prog *child;
+       struct child_prog *child = NULL;
        const struct built_in_command *x;
        char *p;
=================================

to get around the following:

  CC shell/hush.o
/home/rpjday/bbx/busybox/shell/hush.c: In function `run_pipe_real':
/home/rpjday/bbx/busybox/shell/hush.c:1287: warning: `child' might be used uninitialized in this function
make[1]: *** [/home/rpjday/bbx/busybox/shell/hush.o] Error 1
make: *** [busybox] Error 2


rday

p.s.  that warning could be avoided by restructuring the control flow
of that code as well, but i'll go with the easy solution right now.
