Command bar w/ increased size when in fullscreen and tabs

[emaiax]

Using MacVim Snapshot >151 breaks the size of command bar when using tabs.

Prefer native full-screen support, makes no difference here, I tested w/ both options.
I'm using dark mode, but makes no difference either.

Snapshot >152

This is not really a bug per se and is as designed.

When in full screen the screen size is usually not a precise fit for how many number of lines you want to fit (depending on font size). In the snapshot 151 screenshot above you can see that there are black bars and that the tabs are not top-aligned. In 152 it is fixed so that you don’t see black bars (instead the background is filled with background color, read the release notes for it) and that MacVim is always top aligned so the tabs would look right. This does mean the command line is moved up a little bit.

No matter what choice you make in terms of alignment (center or top aligned, black bars or filled with background color) it’s going to look a little weird so it’s just one of those decisions we have to make.

If yoh open GVim on Windows or Linux (GTK) you would actually see similar results when you maximize the window (the command line is not flushed against the bottom).

This is also similar to set guioptions+=k.

@ychin so, I'll close this issue since it isn't an exactly MacVim bug.

Thanks for your answer! ;)

Re-opening issue. With the recent stateful renderer change (#858), we could introduce a new setting to pin the command line to the bottom. I have some work-in-progress experiments on that but not ready for prime time yet, but using this issue to track.
