Re: [PATCH v3 2/5] diff: diff_aligned_abbrev: remove ellipsis after abbreviated SHA-1 value

[Ann T Ropea <bedhanger@gmx.de>]

Neither Git nor the user are in need of this (visual) aid anymore, but
we must offer a transition period.

Also, fix a typo: "abbbreviated" ---> "abbreviated".

v2: rename patch series & focus on removal of ellipses
v3: env var instead of config option, use one-line comments where appropriate, preserve indent level
