For example like this (untested):
AC_ARG_WITH([module],
[AS_HELP_STRING([--with-module-ID=PATH,PRIORITY,SHARE[[,COMMAND
LINE]]],
[add a module])])
If you need non-nested brackets, you can still use quadrigraphs,
see 'info Autoconf Quadrigraphs'.

This breaks if the user of your configure script does
some_var="let's fool configure:
with_module_foo=bar"
export some_var
./configure

This code does not necessarily execute in a subshell, so you need to
save and restore IFS here, for example like this:
save_IFS=$IFS &&
IFS=, &&
read m f p s c &&
IFS=$save_IFS &&

This pair of brackets looks underquoted, too.
