Add suggestion to check block delimiter

Browse source 
The fix for #217 means that blocks of target code delimited by { } with
'#' comments in now give errors (previously these lines were quietly
discarded).

The fix is generally to use %{ %} delimiters instead, so suggest this
might be the issue in the error message to help users hitting this issue
with wrappers which were apparently working before.
