(I'm going through old bug reports that have unfortunately gotten no
responses yet.)

`add-abbrev' doesn't have a doc string itself, but as all the in-tree
callers of this function says:

---
Don't use this function in a Lisp program; use `define-abbrev' instead.
---

So you probably shouldn't use this programmatically, either.

However, it's possible that the `forward-word' should perhaps be
changed, but on the other hand, abbrev.el will probably be deprecated
any year now in favour of nabbrev.el, so I don't think it's a good idea
to change anything here, and I'm closing this bug report.
