better job of finding the real consol device rather than using
/dev/console which doesn't support job control. Patch also
thanks to Eric Delaunay.
+ * more started to read from stdin after the last file was finished, and
+ options were not parsed correctly (fix thanks to Eric Delaunay).
+ * rm wouldn't remove a symlink unless the symlink was valid. This was
+ a side effect of the busybox 0.32 recursiveAction() fix. Things
+ should now work correctly.
+ * grep wouldn't grep stdin. Now it does.
+ * sed wouldn't sed stdin. Now it does.
+ * sed was appending a \n to the end of lines with replacements.
+ Now it doesn't do that.
+ * ls -l now bypasses libc6 nss when displaying user/group names.
+ Now uses my_getpwuid and my_getgrgid.
0.33
* Fixed a bug where init could hang instead of rebooting.
