Previously we were recording output from subprocesses using a multiwriter
and hooking that up to the cmd's stdout to write to both os.Stdout and
a buffer. We would then display the output after the program finished.
This worked well for commands like 'ls' but not for commands like 'vi'
which expect you to be in a tty, and when you've got the cmd's stdout
pointing at a multiwriter, the subprogram thinks we're not in a tty
and then things like terminal corruption can happen. This was the case
with neovim, and even in vim a warning was given with a pause before
starting the program.
Now we're chucking out the multiwriter and instead making it that you
need to press enter after the program has finished to return to lazygit.
This allows you to view the output of the program (e.g. if it's ls) and
then decide that you want to return. It's one level of unnecessary
redirection for editors like vim, but even they could potentially have
output to stderr/stdout that you want to look at before returning.

We were crashing when opening lazygit in a small window because the limit view
was the only view that got created, and there were two functions that referenced
either the 'current' view or the files view, neither of which existed.
Now those functions just return nil if the view does not exist
Return error if the .git exists but is not a directory. This provides a
slightly better failure message for git repo with submodules in case
the '.git' is a file which provides the reference to the parent's .git
folder with the submodule inside.
If your git.skipHookPrefix is set to, say, WIP, in your config, then
hitting 'w' in the files panel will bring up the commit message panel
with 'WIP' pre-filled, so you just need to hit enter to confirm
(or add some more to the message) in order to commit your changes
with the --no-verify flag, meaning the pre-commit hook will be skipped
allows a user to specify a commit message prefix that will tell lazygit to skip
the pre-commit hook. This defaults to WIP. Setting it to the empty string will
disable the feature.
So if my message goes 'WIP: do the thing' then the pre-commit hook will not run
Currently when we want to focus a point on a view (i.e. highlight a
line and ensure it's within the bounds of a view's box, we use the
LinesHeight method on the view to work out how many lines in total
there are.
This is bad because for example if we come back from editing a file,
the view will have no contents so LinesHeight == 0, but we might
be trying to select line 10 because there are actual ten things we
expect to be rendered already. This causes a crash when e.g. 10 is
greater than the height of the view.
So we need to pass in to our FocusPoint method the actual number of
items we want to render, rather than having the method rely on the
LinesHeight, so that the method knows to scroll a bit before setting
the cursor's y position.
Unfortunately this makes for some awkward code with our current setup.
We don't have a good interface type on these state objects so we now
need to explicitly obtain the len() of whatever array we're rendering.
In the case of the menu panel this is even more awkward because the items
list is just an interface{} and it's not easy to get the list of that, so
now when we instantiate a menu we need to pass in the count of items
as well.
The better solution would be to define an interface with a getItems
and getLength method and have all these item arrays become structs
implementing the interface, but I am too lazy to do this right now :)
