range-diff: let '--abbrev' option takes effect
As mentioned in 'git-range-diff.txt': "`git range-diff` also accepts the
regular diff options (see linkgit:git-diff[1])...", but '--abbrev' is not
in the "regular" scope.
In Git, the "abbrev" of an object may not be a fixed value in different
repositories, depending on the needs of the them(Linus mentioned in
e6c587c7 in 2016: "the Linux kernel project needs 11 to 12 hexdigits"
at that time ), that's why a user may want to display abbrev according
to a specified length.
Although a similar effect can be achieved through configuration (like:
git -c core.abbrev=<abbrev>), but based on ease of use (many users may not
know that the -c option can be specified) and the description in existing
document, supporting users to directly use '--abbrev', could be a good way.
