lookbehind assertion regex added in 1.1.2 breaks on safari

[Mark Lussier]

In 1.1.2 (commit 9154e4) the change to split on a regex uses a lookbehind assertion ?<! and this totally breaks on safari with a "Invalid regular expression: invalid group specifier name" error. Safari currently does not support lookbehind assertions.

For now I have rolled back to 1.1.1
