Commit dcf9a434 dcf9a434657b6459a8078842ef63c45695866094 by Sergey Poznyakoff
Options

mhn: compatibility fixes in show mode. 

* mh/mhn.c (OPT_PAUSE): Remove define.
(pause_option): New variable.
(opt_handler): -pause/-nopause sets pause_option.
If stdin is not a tty, set pause_option to 0.
(check_type): New function.
(mhn_show_command): If mhn-show-<type>[/<subtype>] is not set,
use %pmoreproc '%F' for text/plain and message/rfc822 parts.
If content type is application/octet-stream and type=tar, use
tar to list the archive.
Otherwise, complain and return NULL.
(MHN_CONFIRM): Rename to MHN_PAUSE.
(mhn_pause): New function.
(show_handler): The value of pause_option controls the %p escape.
Rewrite the MHN_PAUSE handling to avoid the use of the fixed-size
buffer.  Implement C-c handling, as in other mhns.
If mhn_show_command returns NULL, do not attempt to show the content.
Remove dubious usage of mu_transport_t.
(mhn_store_command): handle application/octet-stream with type=tar.
* mh/tests/mhn.at: Add a test for show mode.

`Twas brillig, and the slithy toves
Did gyre and gimble in the wabe;
All mimsy were the borogoves,
And the mome raths outgrabe.
`Beware the Jabberwock, my son!
The jaws that bite, the claws that catch!
Beware the Jujub bird, and shun
The frumious Bandersnatch!'
He took his vorpal sword in hand:
Long time the manxome foe he sought --
So rested he by the Tumtum gree,
And stood awhile in thought.
And as in uffish thought he stood,
The Jabberwock, with eyes of flame,
Came whiffling through the tulgey wook,
And burbled as it came!
One, two! One, two! And through and through
The vorpal blade went snicker-snack!
He left it dead, and with its head
He went galumphing back.
`And has thou slain the Jabberwock?
Come to my arms, my beamish boy!
O frabjous day! Calloh! Callay!
He chortled in his joy.
`Twas brillig, and the slithy toves
Did gyre and gimble in the wabe;
All mimsy were the borogoves,
And the mome raths outgrabe.
