An alternative would be to teach fmtutil about "depending formats" and
let it skip a format if there is no information for the depended-on
format, just as it would skip that depended-on format itself.

This would be done in the parse_line function in fmtutil, but I'm unsure
about the actual format of $texargs.  It seems that most formats have a
'*' before there ini file, like this:

latex           pdftex         language.dat    -translate-file=cp227.tcx *latex.ini

What does that mean?

But I guess we can just grep for '&\([[:alpha:]]+\)[[:space:]]' in
$texargs (it need not at the beginning, at least unless
-tranlage-file=foo is forbidden when using a preloaded format), and
check for $1.fmt.

But how will jadetex then be recreated when latex becomes available?
