Unexpected Range Behavior With Spaces

[microalps]

This was found while investigating dotliquid/dotliquid#565

Spaces are not accepted consistently.

Template	Status
{{(1.. 5}}	Works
{{(1 . 5}}	Works (unexpectedly)
{{(1 ..5}}	Doesn't Work (Empty)
{{(1..5 )}}	Exception
{{( num.one .. num.five)}}	Works
{{( num.one .. num.five )}}	Exception

I checked shopify/liquid, it seems don't allow any spaces, otherwise will be interpreted as literal string, like "{{(1 . 5}}".

I make invalid uses like {{(1. 5)}} or {{(1..5}} to throw in the 10.20.2, and for backward compatibility spaces are still allowed, before or after numbers.

Thank you for reporting @microalps, happy to find another Liquid enthusiast!

See my tests on https://replit.com/@microalps/LiquidUnitTests#main.rb - it depends if strict mode is on, which allows spaces or lax mode which doesn't. I know, it's a misnomer.
