Fix the -nodraftfolder and -nowhatnowproc options.

The commit 744c4a9c didn't take into account the -nodraftfolder
and -nowhatnowproc options, which can be used to cancel the
effect of the corresponding facilities.  This commit fixes it.

* mh/mh_getopt.c (mh_getopt_ext): New function.
* mh/mh_getopt.h (mh_getopt_ext): New prototype.
(mh_optinit): New struct.

* mh/tests/comp.at: Test the use of Draft-Folder
* mh/tests/forw.at: Likewise.
* mh/tests/repl.at: Likewise.

* mh/comp.c (main): use mh_getopt_ext to properly process draftfolder
and whatnowproc.
* mh/forw.c: Likewise.
* mh/repl.c: Likewise.

* mh/mh.h (mh_whom): Remove.
(mh_whom_header, mh_whom_file, mh_whom_message): New protos.
* mh/mh_alias.y (mh_read_aliases): Don't read aliases twice.
* mh/mh_whatnow.c (whom): Use mh_whom_file.
* mh/mh_whom.c (mh_whom): Rewrite and rename to mh_whom_file.
(mh_whom_header, mh_whom_message): New functions.

* mh/whom.c: Use mh_getopt_ext.  Interpret command line
arguments, depending on whether the draftfile facility is in use.
