[PATCH] maint: remove empty statement after jump label

[Bernhard Voelker]

As discussed in
https://lists.gnu.org/archive/html/bug-coreutils/2011-07/msg00195.html 
empty statements must follow a jump label if the next statement
is a declaration. Therefore, the other way round: the empty statement
can be omitted when no declaration follows.

Have a nice day,
Berny

Subject: [PATCH] maint: remove empty statement after jump label

* src/head.c: removed the empty statement ";" after a jump label,
  as it is only needed when a declaration follows.
* src/kill.c, src/od.c, src/paste.c, src/printf.c: Likewise.
