GNU Coding Standards frown on using "path" for anything but PATH-style
directory lists.  Please use "leading directories" or somesuch here,
as that's what you mean.

This doesn't say relative to what.  It also doesn't mention the
commands which are affected.

The "insert" part is out of place here, since there's no insertion.

How about

  If `diff-add-log-relative-names' is non-nil, file names in the alist
  are relative to the root directory of the VC repository.

instead?
