Subject: Fixed bug in compiler related to pushing ASCII strings to the stack.
X-Git-Url: http://git.subgeniuskitty.com/vvhitespace/.git/commitdiff_plain/971552ffb5ecc3962d54b909f91527ac0e42a2b9?hp=75098baa04f129944fb6d4fc2b4b4e863d49410b

Fixed bug in compiler related to pushing ASCII strings to the stack.
The stream pointer was left at the start of the string since it was walked backward.
Now it properly advances to the end after processing the string.
