No more comments in interpreter specification line!

Hi.

I just backed out revision 1.21 of imgact_shell.c.
As mentioned in commit log, no other operating system has this magic.
I'm also going to MFC it to RELENG_5. Under really big claims, we can
consider MFCing this fix:

	http://people.freebsd.org/~pjd/patches/shell2.patch

which adds backward compatibility for this "feature", but it's ugly and
I'll be glad if we can avoid this.

The commit:

  Modified files:
    sys/kern             imgact_shell.c 
  Log:
  Don't treat # as a comment in interpreter specification line.
  This is magic and no other operating system do so (i.e. Solaris, Tru64,
  Linux, AIX, HP-UX, Irix, MacOS X, NetBSD).
