The default binding for ConfirmInEditor is <a-enter>, which has two problems:
- some terminal emulators don't support it, including the default terminal on
Mac (Terminal.app)
- on Windows it is bound to toggling full-screen
Ideally we would use <c-enter> instead (and Command-Enter on Mac), but neither
is possible without https://github.com/gdamore/tcell/issues/671, so for the time
being add an alternate keybinding which works everywhere.
Show both bindings in the footer of the commit description panel if they are
both non-null. While we're at it, fix the footer for the case where either or
both of the keybindings are set to <disabled>.
And finally, change "commit" to "submit" in that footer; we use the same panel
also for creating tags, in which case "commit" is not quite right.
This makes it possible to use date and time in initial values like this:
```yaml
initialValue: 'ruudk/{{ runCommand "date +\"%Y/%-m\"" }}/'
```
I want to use this to configure my BranchPrefix like this:
```yaml
git:
branchPrefix: 'ruudk/{{ runCommand "date +\"%Y/%-m\"" }}/'
```
It's not an ideal solution because there's no indication of what kind of objects
you can add to those maps or arrays, but at least they show up at all (with a
comment containing a link to more information), and that's already an
improvement.
I'm not mentioning *why* it's not a good idea, and I'm not sure it's important
to explain this to users. I'll say it here:
- it exposes users to potential bugs like the one described in the previous
commit
- if we decide to change the default of an option to something "better" (like we
did with the "show graph" setting), users don't benefit from what we think is
an improvement for most users
This is very similar to the same menu in the Files panel, except that it works
on whatever diff is currently shown in the main view, including range diffs
either in diffing mode (shift-W), or from a range selection of commits.
It has fields .To and .From (the hashes of the last and the first selected
commits, respectively), and it is useful for creating git commands that act on a
range of commits.
When enabled, it adds "+n -m" after each file in the Files panel to show how
many lines were added and deleted, as with `git diff --numstat` on the command
line.
