Whitespace revision, take II

perltidy can result in code formatting which is a little extreme
when left at the 80-characters-wide default, so rejoin the split
$doc->findvalue() calls which were negatively affecting
readability.

Also, Evergreen code standards is for using four spaces, not tabs,
so correct for that small mixup as well.
