* anno.c -- annotate messages

*
* This code is Copyright (c) 2002, by the authors of nmh. See the
* COPYRIGHT file in the root directory of the nmh distribution for
* complete copyright information.
*
* Four new options have been added: delete, list, number, and draft.
* Message header fields are used by the new MIME attachment code in
* the send command. Adding features to generalize the anno command
* seemed to be a better approach than the creation of a new command
* whose features would overlap with those of the anno command.
*
* The -draft option causes anno to operate on the current draft file
* instead of on a message sequence.
*
* The -delete option deletes header elements that match the -component
* field name. If -delete is used without the -text option, the first
* header field whose field name matches the component name is deleted.
* If the -delete is used with the -text option, and the -text argument
* begins with a /, the first header field whose field name matches the
* component name and whose field body matches the text is deleted. If
* the -text argument does not begin with a /, then the text is assumed
* to be the last component of a path name, and the first header field
* whose field name matches the component name and a field body whose
* last path name component matches the text is deleted. If the -delete
* option is used with the new -number option described below, the nth
* header field whose field name matches the component name is deleted.
* No header fields are deleted if none of the above conditions are met.
*
* The -list option outputs the field bodies from each header field whose
* field name matches the component name, one per line. If no -text
* option is specified, only the last path name component of each field
* body is output. The entire field body is output if the -text option
* is used; the contents of the -text argument are ignored. If the -list
* option is used in conjuction with the new -number option described
* below, each line is numbered starting with 1. A tab separates the
* number from the field body.
*
* The -number option works with both the -delete and -list options as
* described above. The -number option takes an optional argument. A
* value of 1 is assumed if this argument is absent.
