[BusyBox] separating multiple sed commands

[Frank Lenaerts]

While migrating from a 0.60.x (busybox 0.60.5 in Debian Sid) to a
1.0.0-preX (busybox-cvs version from 20031212 in Debian Sid,
corresponding to 1.0.0-pre4) busybox, I noticed a difference in the
sed's behaviour.

In the older version, I could use a semicolon to separate sed
commands e.g.:

sed 's/.*key=\(.*\)/\1/ ; s/ .*//' some_file ;

In the newer version, this does not work anymore and I get a "sed: bad
option in substitution" error. When I rewrite the sed commands without
a semicolon however, everything works fine e.g.:

sed '
s/.*key=\(.*\)/\1/
s/ .*//
' some_file ;

This can thus be used as a work-around, but I don't know if the fact
that using a semicolon to separate sed commands results in an error is
the purpose (i.e. a builtin limitation) or not (i.e. a bug).
