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.
SelectedCommit is context-dependent and points to SelectedLocalCommit,
SelectedReflogCommit, or SelectedSubCommit depending on which panel is active.
If none of these panels is active, it returns the selected local commit, which
is probably the most useful default (e.g. when defining custom commands for the
Files panel).
- Introduced a new optional user config command, allBranchesLogCmds
- When pressing 'a' in the Status view, cycle between non-empty, non-identical log commands
- There will always be at least one command to run, since allBranhesLogCmd has a default
- Update documentation & write an integration test
- Update translation string
