Fix unintended lstrip_blocks behavior

Add tests for lstrip whitespace behavior fix

Also did peformance tests for the previous fix and saw no measurable
impact.

Fix unintended lstrip_blocks behavior. Fixes #1138

Introduced in #858. Tests will follow, also results of performance
testing.

Don't use setlocal in syntax file (#1164)

I'm not 100% sure that one should not use `setlocal` in a syntax file,
but this breaks other filetypes that may include this syntax file, like
the vim-markdown plugin.  The `comments` and `commentstring` get set for
that markdown buffer with the jinja settings.
