How come, loading a github project writes strange code change entries for classes
like
LGitFetchOptions
LGitRemoteCallbacks
...

For example, in a Pharo 6.1 image I load bloc like this:

Metacello new
baseline: 'Bloc';
repository: 'github://pharo-graphics/Bloc:pharo6.1/src';
load: #core

In my Epicea code change window I see this entries (see screenshot).
And the final "new" version of this classes, (class definitions) just look like the
original class definition in a fresh image.
