The FS=";" is a pattern expression that is used to match the first line
of input, after it has already been split into fields. It evaluates true
so the block it guards is always run. After the first line has been
dealt with, future lines will be split using the new FS setting. As
another poster supplied, slap the FS setting in a BEGIN-guarded block.

If it's broken really badly - don't fix it either.
