That's why it seems completely fine to you. It's not English. ;-)
"less than" is correct; "lesser than" is not correct.

Oh really? Then all the more reason to explicitly specify the accepted formats
(completely).
You cannot use a function reliably if you don't know what kinds of arguments it
handles.

Of course. That's why I wrote "`version<' ETC." in the subject line.


Also:

3. Specifically state the ordering rule. Wrt alphabetical comparison, don't just
give an example, state that letters are compared alphabetically (and state
whether that's case-sensitive).

4. Mention at least one of these version-comparison functions in the Elisp
manual, node `Version Info'.
