Currently, if a commit message exceeds 72ch and there is space, it still
gets restricted to 72ch.
This is kind of a delicate thing to fix, as the rules are complicated to
get working in all scenarios. This change adds a few things to
alleviate (too) long commit messages with larger screens.
1. If there are no related changes, don't restrict the width of the
commit message.
2. Add an additional css media query for large screen sizes and set the
min width (if there are break points) to a max of 100ch rather than
72. (this is what the max was before c/106843).
There is a slight problem with jankiness if the commit message ends up
getting/using more width, as it has to wait to know whether the related
changes exist before the style is updated. However, the ways in which
all potential use cases can be addressed are very limited.
