Linkifying includes trailing '.'

[rightparen]

Details

Linkifying includes a trailing '.' as part of a URL's path. This can cause problems in the common scenario of a terminal program displaying output that ends a sentence with a URL.

• Browser and browser version: Google Chrome Version 62.0.3202.94 (Official Build) (64-bit)
• OS version: macOS Sierra Version 10.12.6
• xterm.js version: v2.9.2 and current master

Steps to reproduce

1. Run the demo.

2. Enter the command:
   echo "Please see https://github.com/xtermjs/xterm.js/issues."

3. Click the echoed link.

Expected: Link references https://github.com/xtermjs/xterm.js/issues
Actual: Link references https://github.com/xtermjs/xterm.js/issues., which results in 404 Not Found.

To be fair, the current behavior is technically correct, since '.' is a legal URL path character. It's just less usable this way.
