I think that an intuitive way the feature should work may be:
- You started with "git fetch --depth=20" and then later say "I
have only a very short segment of the recent history, but I want
a history that dates back to v1.0" with "--shallow-exclude=v1.0".
In this case, you would be deepening.
- You instead started with "git fetch --depth=20000" that dated
back to v0.5. "--shallow-exclude=v1.0" you say today would mean
"I have very old cruft I no longer look at. I just want my
history lead back to v1.0 and no earlier". In such a case, you
indeed would be making the repository shallower.
I however offhand do not think the feature can be used to make the
repository shallower, and I agree your changes to the usage string
probably describe what the option does more correctly.
I however suspect that the feature is simply buggy and it would
eventually want to allow to shorten the history as well. At that
point we may want to work on the verb 'deepen' there, too.
