Word wrap doesn't work in Git diffs

[ricksanchez]

Word wrap is quite useful features of VS Code in the documents.
However it is broken or not implemented in the git diff view.
This is specially useful here, since the text editor wide is divided by 2.

• VSCode Version: 1.9.1
• OS Version: Ubuntu 16.04

Steps to Reproduce:

1. Edit a document with long lines
2. go to git ctrl+shift+g
3. Compare the document
4. You will see the horizontal scroll bar, and not wrapped text
5. Press Alt+z (no effect)

alt+z and editor.wordWrap do not work at all for me in 1.9.0 and 1.9.1 (see #20174), however when in diff mode I've never gotten any of the wrap settings to work (editor.wrappingColumn, editor.wordWrap, or editor.wrappingIndent). I would like to see diff mode support all 3 of these settings.

Currently Using:

• VS Code Version: 1.9.1
• OS Version: Windows 7

In my opinion the behavior should be something like the following:

wordWrap	wrappingColumn	Effect
false	any value	no wrapping at all
true	<= 0	wrap at viewport
true	> 0	wrap at specified column

If vscode adopts the behavior in this table, the defaults would be editor.wordWrap: true and editor.wrappingColumn: 300.

I find it non-intuitive and confusing that when wordWrap is false there is sometimes wrapping, and when wordWrap is true there is sometimes not wrapping.

Also, the following extension may be useful:

https://marketplace.visualstudio.com/items?itemName=BillStewart.set-wrapping-column

The purpose of the extension is to let you easily change the wrappingColumn setting without a need to edit the workspace or global settings.json file.
