1c845e0bd5 acme, sam, samterm: remove weird switch usage 
For whatever reason all three of these programs
contain switches like:

	switch(x) {
	case 1:
		if(cond)
	case 2:
			f();
	}

Like Duff's device, this is legal C but more obscure
than it really needs to be.

This commit assumes those are intended as written
and simply writes them more clearly. I did consider
that maybe they are mistakes, but in the case of sam/regexp.c,
my rewrite in this commit matches the acme/regx.c that
has been in plan9port since I added acme in 2003.
(I didn't bother to dig up the old Plan 9 releases.)

Assuming acme/regx.c has been correct for the past
two decades, this commit should be correct too.

Remote whitespace at the ends of lines.
Remove blank lines from the ends of files.

are not executable.

Otherwise io.c:39 compares int != ulong,
causing spurious file modification warnings
