Bug 29771: Scalar context for split

This patch tackles a very specific scenario. Calling split(...,
CGI::param) makes it be called in list context. The split docs say:

split /PATTERN/,EXPR,LIMIT

this means the first CGI param will be used as EXPR and the second one
as LIMIT, which is wrong anyway. So the fix is to just force scalar
context.

To test:
1. Not sure, just make sure nothing breaks when using the scripts in the
   browser.
