`diff.autoRefreshIndex`::
When using `git diff` to compare with work tree
files, do not consider stat-only changes as changed.
Instead, silently run `git update-index --refresh` to
update the cached stat information for paths whose
contents in the work tree match the contents in the
index. This option defaults to true. Note that this
affects only 'git diff' Porcelain, and not lower level
'diff' commands such as 'git diff-files'.
