It's for cases when we're not supposed to output something on the
command line, e.g. when called for a file redirection, or something.  Or
in eshell scripts.  Or when called non-interactively, or by another
function.  John will know better.  :)

Anyway, what it does in eshell/make is to tell Eshell to use the real
make ("*make") instead of the Emacs compile interface in such cases.

If not called with output focus, just return the command, separating the
command itself from its arguments.  Not sure if it really works though.

If Eshell recognizes numbers in the argument list, it passes them as
numbers to Lisp functions (not as strings).

| 
|   (put 'find-file 'eshell-no-numeric-conversions t)
| 
| Any function with the property `eshell-no-numeric-conversions' set to

The usual No Expert(tm) disclaimer applies, of course.
