Support HTML start tags with new-lines in them.

[tommie]

HTML5 Start tags can contain "one or more space characters" (8.1.2.1 #3).

A "space character" is space, tab, LF, FF or CR (2.4.1).

This change makes marked support any Unicode white space in tags by restricting
the autolink to not contain any /\s/ character. It is slightly more permissive
than the HTML5 standard, but that is unlikely to be a problem in practice.

Closing as stale and merge conflicts.

[tommie]

As you wish. Though marked still doesn't support this, so wouldn't it be better if we got it merged?

(There was no point in me keeping the branch mergeable when I don't see a hint that it will be merged before the next conflict pops up. GitHub didn't send me a notification about your label changes in December.)

Hey @tommie. Yeah. Understand. See #956. I'm also not sure if it has been fixed since reviving the project...I seem to recall a fix for something like this by either @Feder1co5oave or @KostyaTretyak...what version are you using that still doesn't support this? just want to make sure.

[Feder1co5oave]

Looks good to me... Autolinks should not contain whitespace: http://spec.commonmark.org/0.28/#absolute-uri

I'd like to see more test cases to show this though

[tommie]

#956 is great news!

what version are you using that still doesn't support this?

Three years later, I'm not really sure. I was using it through Polymer's , and that was probably before Polymer v1. Polymer v2 exists now. I just looked at the code, and it seemed the regexp still wasn't looking at all whitespace characters.

I'd like to see more test cases to show this though

@Feder1co5oave, I'm showing the new functionality works, and old tests show there is no change in existing behavior. What type of tests would you like?
