Add option to remove column width limit

[ljharb]

I have a 15" screen with thousands of pixels of horizontal resolution - I'd love an option to disable column width truncation so I can see everything.

In addition, it'd be awesome if it could be truncated with … instead of ... :-)

Currently, you can use the --<property>-width options to widen columns beyond the default width. These also work in your ~/.twigconfig like this:

branch-width: 50
status-width: 10

I've done a few experiments to make columns auto-adjust, but it slows things down noticeably. The middle ground might be to continue defaulting to a fixed width so that Twig is fast out of the box, but add --<property>-width=auto support for opting into potentially slower auto-adjust modes.

As for the ellipsis, I actually tested … in a very early version. It looked like an underscore in monospace fonts, so I switched to three dots.

An opt-in switch for a potentially slow feature, that can be optimized in the future, would work great for me!
