Git will add the actual diff to the message displayed in the editor.
This allows to consult better what was actually done and to make use of
code completion features like that of Vim.

Note that with --amend (`cma` alias) the behavior is that the final
diff is shown, i.e. not just the amendment.

Also it's intentionally not used by default message aliases as these
are intended for express and/or ad-hoc commits (so far).

Preserve comments and empty lines to allow for better orientation in
the merged list.

... so that bookmarks have precedence if included in dmenu.

Not particularly bright idea.

For some reason this has always been confusing me.

Could be :1 or more, explicitly providing it seems only useful from outside the actual X session

Too much volatile for git

With transition to tiled window managers, tabbed makes less sense.

Name function right in the first place, instead naming it wrong and
renaming it using alias.
