ADDRESS is the email address for the package's maintainer. PKGNAME is
the name of the package (if you want to include version numbers,
you must put them into PKGNAME before calling this function).
Optional PRE-HOOKS and POST-HOOKS are passed to `reporter-dump-state'.
Optional SALUTATION is inserted at the top of the mail buffer,
and point is left after the salutation.
VARLIST is the list of variables to dump (see `reporter-dump-state'
for details). The optional argument PRE-HOOKS and POST-HOOKS are
passed to `reporter-dump-state'. Optional argument SALUTATION is text
to be inserted at the top of the mail buffer; in that case, point is
left after that text.
This function prompts for a summary if `reporter-prompt-for-summary-p'
is non-nil.
This function does not send a message; it uses the given information
to initialize a message, which the user can then edit and finally send
(or decline to send). The variable `mail-user-agent' controls which
mail-sending package is used for editing and sending the message.
