The tag content should allow non-alphanum characters. See the spec for
section tag content [1]:

These tags' content MUST be a non-whitespace character sequence NOT
containing the current closing delimiter; ...

For the 3 added test cases, #1 and #3 will fail today, and #2 will
trigger a panic. The code change fixes them.

The expected behavior can also be verified on
http://mustache.github.io/#demo, with Mustache:

1: {{#key*}}{{.}}{{/key*}}
2: {{#key}}{{*}}{{/key}}
2: {{#key}}{{*}*}}{{/key}}

and JSON:

{
  "key*": "value*",
  "key": "value",
  "*": "star",
  "*}*": "fish"
}

We can get output as:

1: value*
2: star
2: fish

@alexkappa I understand that you are very busy, I'm not trying to push you :)
