Delta should be aware of diff.noprefix option (truncated filenames)

[wookayin]

The diff.noprefix option (e.g. git config diff.noprefix true) would strip away prefixes such as a/ b/. When this option is enabled, the first two characters of filename would be stripped away even though they are a part of normal filenames.

Expected output: (without diff.noprefix)

package/filename.py
────────────────────────────────────────
...

Actual behavior:

ckage/filename.py
────────────────────────────────────────
...

Tested on 0.0.17.

Although we could configure so that this option is turned off when using delta as pager, delta should be aware of this option and strip prefixes only if the first two letters are git prefixes.

Thanks @wookayin, I agree. Sorry for being slow, I missed the notification here. This sounds like it should be an easy change.

That should be fixed in master. If a user has git.noprefix = true, and also has directories genuinely named "a" or "b", then there will still be incorrect stripping.

Thanks! Yeah, I can imagine the corner case but should be fine for the most cases.
