[BusyBox] bug#1027: Make sed s//p compliant with GNU sed

[Mark Whitley]

Package: busybox
Version: v0.47pre
Severity: normal

Mark Ferrell <mferrell at mvista.com> was gracious enough to patch sed to support
the 'p' option in substitution commands. It does, however, have a little bug
where it prints the appropriate output only once rather than twice as per GNU
sed. Consider:

$ echo "Foo Bar" | sed 's/ Bar//p'
Foo
Foo

$ echo "Foo Bar" | ./busybox sed 's/ Bar//p'
Foo

For the pedants out there, yes, this behavior actually is POSIX compliant, but
when in doubt on a busybox tool, the rule is to emulate the equivalent GNU
tool.

Mark (Ferrel) said he would be responsible for this one.
