error on 2 links without whitespace

[ophilon]

thank you for wonderful gem.
come accross this error while scan the .md file:

echo 'at [https://github.com/learnbyexample] (https://github.com/learnbyexample)'|ruby -rcommonregex -wne 'puts CommonRegex.get_links($_)'
https://github.com/learnbyexample
https://github.com/learnbyexample

works fine. The same without whitespace hungs until ^C:

echo 'at [https://github.com/learnbyexample](https://github.com/learnbyexample)'|ruby -rcommonregex -wne 'puts CommonRegex.get_links($_)' 
^C/home/ophil/.gem/ruby/gems/commonregex-0.1.1/lib/commonregex.rb:63:in `scan': Interrupt
