M books/system/doc/acl2-doc.lisp
M doc.lisp
M emacs/acl2-doc.el

Log Message:
-----------
Avoid a possibly-undefined function in acl2-doc. Avoid ACL2 customization file in "make DOC".

Changed code in acl2-doc to avoid the use of function cl-position,
which isn't available in every reasonable Emacs. Thanks to Eric Smith
for reporting this problem.

Quoting :doc note-7-4:

An ACL2 customization file is no longer loaded by default (when it
exists) when invoking `make' from the top-level ACL2 directory.
This change is not necessary for `make regression' because the
build system for the books already takes care of it. However we
need this change for `make DOC', at the least; thanks to Eric Smith
for bringing our attention to a failure of `make DOC'.
