-- >8 -- gitcli: contrast wildcard given to shell and to git People who are not used to working with shell may intellectually understand how the command line argument is massaged by the shell but still have a hard time visualizing the difference between letting the shell expand fileglobs and having Git see the fileglob to use as a pathspec.
I think this is an improvement, but...

Look at the paragraph below your addition. It is typographically outside of the bulleted list you are adding to, but it really makes sense directly after the prior two bullet points, which are explicitly about disambiguation between revisions and paths. Your addition splits them apart. Does it make sense to join that final paragraph into what is now the third bullet, and then add your new text (the fourth bullet) after? -Peff
