Move SetContentLineCount into OverwriteLinesAndClearEverythingElse. Calling it
separately beforehand is not concurrency safe; we need both to happen
when the view's writeMutex is locked.
It is possible to scroll the selection out of view using the mouse wheel; after
doing this, it would sometimes scroll into view by itself again, for example
when a background fetch occurred. In the files panel this would even happen
every 10s with every regular files refresh.
Fix this by adding a scrollIntoView parameter to HandleFocus, which is false by
default, and is only set to true from controllers that change the selection.
This fixes a crash in an interactive rebase when there's a merge command in the
rebase-todo file that doesn't have a comment. I don't know under what
circumstances this can happen; git itself doesn't produce these, but it is
theoretically possible for the user to do this manually by doing `git rebase
--edit-todo`, or third-party tools could do it too.
We had one user report a crash because of this, so it seems worth fixing it.
Adaptions are for this gocui commit:
Cleanup: remove Is* error functions
- Use errors.Is instead of quality comparisons. This is better because it
matches wrapped errors as well, which we will need later in this branch.
- Inline the errors.Is calls at the call sites. This is idiomatic go, we don't
need helper functions for this.
See https://go.dev/blog/go1.13-errors for more about this.
Since they started releasing .0 versions with 1.21.0, the go version
need to be a full release version specifier and not a go language
version. They relented and added support for defaulting to a .0 release
if none is specified in later 1.23.x releases, but for users with local
1.21 or 1.22 toolchains the lack of a full release specifier breaks
them. And going forwards this is more technically correct anyway.

This updates gocui to include https://github.com/jesseduffield/gocui/pull/68 and
https://github.com/jesseduffield/gocui/pull/69, which changes views to not have
an extra blank line at the end when content ending in a newline character is
written to them. This makes text views more consistent with list views, which
don't have a blank line after the last list entry either.
Original commit message of the gocui change:
This fixes View.Size, Width and Height to be the correct (outer) size of a view
including its frame, and InnerSize/InnerWidth/InnerHeight to be the usable
client area exluding the frame. Previously, Size was actually the InnerSize (and
a lot of client code used it as such, so these need to be changed to InnerSize).
InnerSize, on the other hand, was *one* less than Size (not two, as you would
have expected), and in many cases this was made up for at call sites by adding 1
(e.g. in calcRealScrollbarStartEnd, parseInput, and many other places in the
lazygit code).
There are still some weird things left that I didn't address here:
- a view's lower-right coordinates (x1/y1) are one less than you would expect.
For example, a view with a 2x2 client area like this:
╭──╮
│ab│
│cd│
╰──╯
in the top-left corner of the screen (x0 and y0 both zero) has x1/xy at 3, not
4 as would be more natural.
- a view without a frame has its coordinates extended by 1 on all sides; to
illustrate, the same 2x2 view as before but without a frame, sitting in the
top-left corder of the screen, has coordinates x0=-1, y0=-1, x1=2, y1=2. This
is highly confusing and unexpected.
I left these as they are because they would be even more of a breaking change,
and also because they don't have quite as much of an impact on general app code.
