Commit 7717d6fa 7717d6fab8dd9168864990714574a82aa85f7229 by Sergey Poznyakoff

mh: improve traditional option parser and help output.

* mh/mh_getopt.h (mh_option): Move match_len to the end of the
structure.  It should not be initialized.
(mh_option_init): New prototype.

* mh/mh_getopt.c (mh_option_init): New function.
* mh/mh_argp.c (mh_argp_parse): Call mh_option_init.

* mh/ali.c: Update mh_option declaration.
* mh/anno.c: Likewise.
* mh/burst.c: Likewise.
* mh/comp.c: Likewise.
* mh/fmtcheck.c: Likewise.
* mh/folder.c: Likewise.
* mh/forw.c: Likewise.
