[BusyBox] (no subject)

[Christophe Boyanique]

Hello,

Here is a patch against the current cvs. It adds a fake applet egrep that
is an alias to grep. It increases the size of busybox about 54 bytes (with
trivial help defined) and is disabled by default.

I made this one because lots of script expect egrep to work and I cannot
modify all of them...

Christophe.
