Web Inspector: Entering ":n" in Open Resource Dialog, where n > number of lines, should jump to the last line

[Nikita Vasilyev]

Steps:
1. Open Inspector on this page.
2. Press Command-Shift-O
3. Type "global.js:99999999"

Expected:
global.js opens and focused on the last line.

Actual:
global.js opens and focuses on the previously focused line (or just scrolls to the top of the resource).

Notes:
This is how it works in Sublime Text and Chrome DevTools.

How does this handle editors that haven't yet loaded content (initial string not set, defer reveal)?

Is lineCount() zero, and so line would be -1, and lineHandle would not exist?

On the surface this patch seems fine, but I worry that if "deferReveal" is true, we would have just lost the line number.

The test scenario for this is click a link to reveal a position in a resource that will be automatically pretty printed.

This feels right! I'll review more closely when at a computer.

r=me, I like this much better. Thanks for addressing the comments.

To be sure, did you test with a an auto-formatted resource? Let me know if you have questions.
