Option to diff against specified commit

[jokem59]

It would be nice if there was an option to diff against a specific commit (e.g. diff off of the commit that a branch was forked from). I'd imagine that this setting would be applied globally if set.

It would make tracking all changes a little easier if one tends to use many small commits vs one large commit.

There's the function git-gutter:set-start-revision:

git-gutter:set-start-revision is an interactive compiled Lisp function in
‘git-gutter.el’.

(git-gutter:set-start-revision START-REV)

Set start revision. If ‘start-rev’ is nil or empty string then reset
start revision.
