Parser incorrectly reading strong/emph in paragraphs that contain links.

[eclbtownsend]

The following input produces an incorrect syntax tree:

const char* sampleInput = "*text* [link](google.com)";
cmark_node* cmark_root = cmark_parse_document(sampleInput, strlen(sampleInput), CMARK_OPT_DEFAULT);
const char* html = cmark_render_html(cmark_root, 0);

This produces a tree:

<p>*text* <a href="google.com">link</a></p>

I would expect text to have emphasis tags. It seems to only miss the last set of emphasis before the link. try "*text* *text2* [link](google.com)"

Curious. I can reproduce with the cmark command line tool:

% build/src/cmark
*text* [link](google.com)
^D
<p>*text* <a href="google.com">link</a></p>

And this is a regression -- I tried with an older version and didn't see this.

Bisecting shows that this bug got introduced with commit ed0a4bf8a0c5ef52e8d70ce032f2429d32debefa (fix for #389). @nwellnhof can you take a look?
