[PATCH] dim: Fixes/polish for cherry-pick

[Daniel Vetter]

- Subcommands without subshell is nice, except it can break worktree
  setups: Branch specific commands want to run in the worktree,
  general commands like dim_cite switch back to the main directory.
  Tears ensue (or well, some cryptic complaint from git that
  cherry-pick --abort failed because there's no cherry-pick in
  progress). Run it in a subshell.

  Not sure we need a general fix to make this more robust.

- Document commands a bit better.
