Fixes #162

The regex wasn't matching the line. I think Atom use to includes newlines on to the beginning of text buffers, this is no longer the case. This fixes the Wrap Lines command.

Edit: Actually, looks like due to Atom's reporting system, #162 is actually an accumulation of multiple errors, all with the same error message Uncaught TypeError: Cannot read property '1' of null - this PR will resolve the issues regarding the wrap lines function, but not all reported in that thread. The issue should remain open.

Thanks for your PR! You're right #162 is a real mess. I tried to sort it out and added a comment which should give an overview.
Could you please explain how to reproduce the error you are fixing with this?

[jonathanrdelgado]

@MoritzKn Yeah, sorry for not including the repro.

• Add the following code to a JavaScript text editor. (This works in other languages as well)

/**
 * This is a horribly long comment that should wrap because I will have to scroll horizontally to see the entire thing because it is so long
 */

• Have your Preferred Line Length in Atom settings be around 80, which is the default. Esentially, enough for the sample text to be longer than the line length.
• Select anywhere in the sentence
• Run the Docblockr: Wrap Lines command
• Will throw Cannot read property '1' of null which can be traced back to the change made

I went through the stack trace, this line causes the error. I noticed that the text variable in that scope didn't have a leading line break, which caused the match on line 583 to fail.

As per the cause of this, I think Atom use to include a newline when getting buffer regions, this is no longer the case.

Also, was just searching for any other lingering issues on this matter, found #28 which actually implemented this same fix, but wasn't merged because it included another odd function - not sure what value it added over Wrap Lines at face value.

Fixes #16

Ok, thank you! Good research, I appreciate that. 😄

[MoritzKn]

Released with version v0.8.7.
