Hmm... why did you choose explicit-shell-file-name over shell-file-name?

It was mentioned by Michael as a possibility. I chose it because is a
defcustom: it might reflect an user preference compared with
shell-file-name which is given.
For example, my shell-file-name is bash. I might customize
explicit-shell-file-name to '/bin/zsh', then i can
use '**/' zsh syntaxis in the wildcard expansion:
(let ((buf
(dired-noselect (expand-file-name "**/*.el" source-directory))))
(with-current-buffer buf
(dired-toggle-marks)
(length (dired-get-marked-files))))
=> 1731
;; => 277 ; If i would use shell-file-name
We might changed it if you don't like it.

explicit-shell-file-name is normally used when the user asks for a shell
(e.g. M-x shell), whereas shell-file-name is used whenever we want to
run a shell command (e.g. `shell-command`).
The docstring of `shell` says:
Program used comes from variable `explicit-shell-file-name',
or (if that is nil) from the ESHELL environment variable,
or (if that is nil) from `shell-file-name'.

But setting explicit-shell-file-name to `/bin/zsh` doesn't let you use
`**/` in M-! whereas if you had set shell-file-name to `/bin/zsh` you'd
get that extra functionality everywhere.

I'd also lost the extra bash functionality everywhere :-)
