Line substring is redundant when spaces are present

[Cubified]

markdown-parse/MarkdownParse.java

Line 22 in 34a4c89

link = link.substring(0, link.indexOf(" ", openParen));

The value stored in link from the first time substring() is called gets overwritten by the second time substring() is called, making the first call to the method redundant.

To fix, add an else block around the second substring(), or add a trim() to link.

A test that breaks is:

[hello](world.com)    <-- There are spaces

1) testGetLinks_testFile10(MarkdownParseTest)
