Adjust Git Status Parsing to Better Handle Null Chars

[thecoolwinter]

Description

Fixes an issue with git status parsing where the substring indexing was off-by-one when creating the file string due to an index being incremented before creating a substring.

Fixes this by incrementing the current string index after returning the correct substring.

The related issue is marked as a Tahoe bug, the Tahoe bug is that Tahoe now shows the null character as a %00 at the end of the label, where previous macOS versions did not. This change is retroactive however as it is a bug fix.
