#17719: Improper parsing of template block and variable tags

---------------------------------+--------------------
Django template parsing (Lexer) looks for the first occurrence of %} after
a {% when determining what a block tag is. This prevents the use of "%}"
as a string literal. So a template syntax error will be raised for the
following valid expressions:
{{{
{% include "template.html" tvar="Some string literal with %} in it." %}
{% with tvar="Some string literal with %} in it." %}{% endwith %}
}}}
This is also true for variable tag parsing. Example:
{{{
{{ some.variable|default:"}}" }}
}}}
If this is expected/intended behavior, it doesn't appear to be documented
anywhere.
The actual fix doesn't look trivial, but shouldn't be too bad. I could
help with a fix if there's interest in that.
