That'd declare regular releases as MAJOR.0 in the version field, which
I'm not sure if we want that.  In the case of random commits I'm less
reserved, as they don't correspond to releases anyway.

You could define that file-union right after ijconsole.  If you want to
golf even more, you could define ijconsole inside that file-union, i.e.
  (define jsoftware-aux-files
    (file-union "jsoftware-aux-files"
      `(("profile.ijs" ,(search-aux-file ...)
        ("ijconsole" ,(program-file ...))))

I'm not quite sure if you want to use jsoftware-aux-files directly as
input or whether it's wiser to stuff it into another union like 
(file-union "jsoftware-aux-input" `(("aux" ,jsoftware-aux-files))).
search-input-file will probably do the right thing regardless.
The new style should also still work with assoc-ref, it'd just be
weirder to look at.  Lastly, you could code up a (search-file-input)
just in case; I'm not sure if we have one already.
