* Wrote sed -- weighs only 1.8k (5.8k with full regular expressions!).
* Fixed a stupid seg-fault in sync
* Fixed mount -- mount -a failed to parse and apply mount options
* Fixed umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
* umount -a no longer umounts /proc
* Added BB_MTAB, allowing (at the cost of ~1.5k and the need for a rw /etc)
folks to use a real /etc/mtab file instead of a symlink to /proc/mounts.
mount, and umount will add/remove entries and df will now use /etc/mtab
if BB_MTAB is defined.
* Fixed a nice bug in recursiveAction() which caused it to infinitely
hunt through /proc/../fd/* creating new file descriptors if it
followed the /dev/fd link over to /proc. recursiveAction() now
lstat's the file when followLinks==FALSE so it won't follow links
as the name suggests. Fix thanks to Matt Porter <porter@debian.org>.
