rules with $4 or $9 and ^4 or ^9 dropped

[Kgx Pnqvhm]

Change the rule to
$0
$1
$2
$3
$4
$5
$6
$7
$8
$9

I get
word0
word1
word2
word3
word5
word6
word7
word8

in v0.38, Windows 64-bit version.

Changing the rule.txt file to
$1
$2
$3
$4
$5
$6
$7
$8
$9
$0

gets:
word1
word2
word3
word4
word6
word7
word8
word9

so its skipping lines, not characters.

(And now v0.37 won't work, saying its outdated. But at least it processed all the rule lines, so my mangles counts came out OK.)
