Subject: bug#52428: 28.0.90; Eshell complains that `processp' is unbound on MS-DOS

On MS-DOS, start eshell, and type any command that will result in a
synchronous subprocess being started:

c:/djgpp/bin $ djecho hello

Eshell will complain that `processp' is unbound, because there are two
uses of `processp' in `eshell-eval-command' that need to be replaced
with `eshell-processp'.
