E3-1203: Fix issue where modifying certain wrapper files would cause failure

The issue was that git status --porcelain formats its output in such a way that make no longer passes the variables correctly. The solution is simply to no longer pass the git status data.

Note that the git status data already was not that sufficient in terms of recognising what changes had been made, since all it provided was information as to which files had been modified, not how they had been modified.
