I can still never remember the git equivalents for things like ‘hg log -r default:feature-branch’ or ‘hg diff -c <commit>’. People who haven’t used Mercurial really have no idea how pleasant a VCS interface can be.
The latter is 'git show <revision>', show being one of those fun commands that does a bazillion different things depending on what the argument is. My fun example of what's-the-git-command is 'hg cat -r <commit> <path>', whose git commit equivalent is another variant of 'git show'
