"package" statements aren't highlighted if anything proceeds it on the line

[alexchandel]

These are all perfectly legal package statements:

package Foo;
; package Foo;
eval {package Foo;}
eval {
    ; package Foo;
};
package Foo; package Bar;
;package Foo; package Bar;

GitHub's highlighting of Perl is pretty trash, but these are common in Perl code in the wild.
