tab completion problem in find-file?

[sen_ml]

A friend brought my attention to the following completion related
issue.

To reproduce:

  1) Create two files w/ names "a.log" and "a.log.old" in an empty
     directory, say "~/tmp".

  2) In Emacs, execute C-x C-f (find-file).

  3) Attempt tab completion after typing "~/a." (no double quotes
     of course).

  4) Note contents of minibuffer.

My minibuffer contains:

  Find file: ~/a.log.old

shouldn't that be:

  Find file : ~/a.log

?

I tested this on Emacs 20.7.1.
