I don't promote name-dropping; and <fileTYPES> are often detectable
from their initial bytes [? magic numbers?].

But your statement implies that job.sh SHOULD be handled the same
as jobDOG is 'not good'. That loses a complete dimension.

An extreme case is my ChineseButtonAudioPlayer: it
doesn't even distinguish between directory-nodes.
Apparently it just examines all the files [including <dir-pointers>]
and if it finds one of the File-types-that-it-plays, it plays
that file.

I know for a fact that `mc` pays special attention to <file extentions>.
