literalMidWordUnderscores changes behavior of '*'

[twitwi]

This is probably not a first priority issue.

Considering the following markdown: pointer *ptr *thing​ (I'm not sure how it should be interpreted).
Toggling the literalMidWordUnderscores options unexpectedly changes the rendering:

• without the option, stars remain un-transformed
• with the option, stars are considered as emphasis

@twitwi thanks. I will look into this as soon as possible.

No problem, it's more something I stumbled upon in a very special situation.
Actually #196 happens more often in my use cases (but might be trickier, from my first experiments with showdownjs source code)
