Hi @rocketraman ! thanks for putting these together! I'm "watching" this Gist but I noticed that I don't get notifications when you push new changes, I guess because notifications are only sent when people comment on the Gist. So it'd be awesome if you could just add a small note as a Gist commentary when you add new aliases (if you have time - don't worry if you don't) :)

Cheers!

Thanks @phil-blain. On that note, I've just pushed a bunch of changes:

Hey @rocketraman! I think it could be good to document (either here or on https://github.com/rocketraman/gitworkflow) in what cases

git mergedtopiclg <hash> upstream/master

gives a different answer than a simple

git lg <hash>^-

which in addition to also showing the merge commit, shows only the changes which were actually merged in  <hash>, i.e. if the same branch was merged several times, with additional commits each time, mergedtopiclg always shows all commits on the branch whereas the <rev>^- syntax only shows which commits were merged in <rev>.

What do you think?

@phil-blain, that's cool. I wasn't aware of that syntax. For others that syntax might be new for as well the <rev>^-[<n>] syntax is for the log of rev, including rev itself, and excluding the nth parent (where n defaults to 1). See https://git-scm.com/docs/gitrevisions#_other_rev_parent_shorthand_notations. Thanks for the information.

Added mergedrevs alias with the <hash>^- syntax suggested by @phil-blain.

Updated hl and hlp aliases (see https://stackoverflow.com/questions/61510067/show-specific-commits-in-git-log-in-context-of-other-commits) to handle relative paths.
