Remove extra space before links

[ehsandarroudi]

As already described in issue #56, given:

(<a href="http://foobar.com">link</a>)

I would expect to see:

([link](http://foobar.com))

But the actual result has an extra space after the left parenthesis:

( [link](http://foobar.com))

The implementation also handles the case when there is an exclamation mark before the link (by adding a space).

is there any reason not to merge this one? @xijo

[ehsandarroudi]

I'm not sure if there are any practical cases left where an exclamation point before the link would be concatenated without a space in between (and thus make it an image).
The second commit (966e3d7) deals with cases like this:

<span>!</span><span><a href="http://link.com">link</a></span>

Please let me know if there's anything else I can improve.

@Easy-D @eturino Thanks for the reminder, you're right. I'll merge it right in and release it soon. Thanks for your contribution!

thanks @Easy-D and @xijo.

Any plans on releasing a version with this change?

[xijo]

@eturino I wanted to wait for another PR to get finished, but if you're waiting for it here you go: released as 1.0.2

@xijo thanks a lot! 👍
