Make ↩ suffix optional in multiline commit messages

[infotexture]

Recent versions append the ↩ character to multiline commit messages in the All Commits view.

In repos where all messages include a message body, this extra character is just noise that makes it harder to parse the information at the end of the subject line, which often end with issue numbers or other critical details.

This seems like the sort of thing that would best be optional, like the -/+ marks in diffs, or the * in tabs with uncommitted changes.

After some thought, we came to the conclusion that even in a repository where every commit has a description, it is important to have the description icon. Sometimes, no icon is also important, and can mean some kind of user mistake.

In the end, we made the icons smaller, so they were less of an eyesore.
