URL support not working on Mac OS X

[bwklein]

Report from @chuckf originally on https://github.com/bwklein/asciidoc-image-helper/issues/20

Using Atom 1.7.3 and asciidoc-image-helper 0.9.2, when I paste a path to an image file that path pastes in and does not convert to an image:: link as expected.

The test path I have used is:

/Users/chuckf/Downloads/splunk.png
/Users/chuckf/Downloads/splunk.jpg

Expected result is

image::splunk.png
image::splunk.jpg

Actual result:

/Users/chuckf/Downloads/splunk.png
/Users/chuckf/Downloads/splunk.jpg

NOTE: When pasting similar paths on a Fedora box, same versions of the software, the URLs are converted to image:: links as expected.

I don't get a success or error message popup.

I opened the console window with cmd-alt-i (for future reference) and did not see any errors occur when pasting in the link.

I typed the paths into a text editor, HTML page, and ran the command ls /Users/chuckf/Downloads/splunk.png into the native terminal and iterm2. I then selected the text and copied using cmd-c and pasted into Atom using cmd-v.

Just tried it out and can confirm the issue. This functionality did work previously. Small caveat: I just restructured my package install, which might have been messing things up. (but of course no way to verify 😉 )

I think that it might be how we are handling the string in Line 88.

Then this commit would have messed things up? c1e4fe7

Should be fixed in #13
