The files have a nice marker early on, so the archive-exe-p I proposed
is
        - only .exe filename
        - "MZ", which is a DOS exe
        - "LHA's SFX", as tested by the "file" command

It'd be possible to add the search through the file looking for
"-lh5-" which is the start of the archive part proper (per
archive-lzh-exe-summarize), but I expect "LHA's SFX" is enough (it's
in a spot which I think is normally either "reserved" or relocation
table).

Can my archive-exe-p func go in, even if it's not enabled, so that
those who are confident about that test can customize it into the
magic alist?

In which case could .exe or lzh .exe or whatever get a mention in
files.texi, so that it's not a secret?
