MultiRegionHighlighter provides a way to segment the buffer in
logical regions using the common left-most rule for finding the
next region. It then provides highlighting groups for each region
that can be filled.
An optional parameter defines the recursion regex, that match

For example, %sh{ ... } blocks support nested { }, so defining \{
as the recurse regex make the region highlighter correctly match
%sh{ ... { ... } ... } constructs
