The command's help text says "Abandon a revision", which I think is a good indication that the command's name should be `abandon`. This patch renames the command and other user-facing occurrences of the word. The remaining occurrences should be removed when I remove support for evolution.

# Comparison with Git

TODO: Describe the differences compared to Git here

|
## Command equivalence table
|
|
|
|
Note that all `jj` commands can be run on any commit (not just the working copy
|
|
commit), but that's left out of the table to keep it simple. For example,
|
|
`jj squash -r <revision>` will move the diff from that revision into its parent.
