Log Message:
Jumbo mail patch from our anonymous user:

1) Use editline [optional]:
   Most of this code was borrowed from src/usr.bin/ftp.  It does the
   appropriate editing, history, and completion for all mail commands
   (from cmdtab[]) and also does editing on header strings ('~h' inside
   the mail editor).

2) '-B' flag:
   This will suppress the "To:" line passed to sendmail.  In most
   configurations it will lead to sendmail adding "To: undisclosed
   recipients;".  Currently, AFAIK mail requires at least one exposed
   recipient address.

3) Comments in rcfile:
   Currently, comments in .mailrc are only supported if the first
   (non-white) character on a line is '#' followed by white space,
   i.e., '#' is a 'nop' command.  This (trivial) patch allows the more
   normal/expected use of '#' as a comment character.  It does not
   respect quoting, so that might be an objection which I should fix.

4) Sendmail option editing:
   This adds the sendmail option string to the strings editable by the
   '~h' command within the mail editor.  Currently, you can only set
   this string from the command-line, which is particularly annoying
   when replying to mail.

5) Reply from:
   When replying to a message, grab the "To:" address from the message
   and, if there is only one such address and it does not match a list of
   allowed addresses (set in the "ReplyFrom" variable), pass it to
   sendmail as the "From:" address for the reply (with the '-f' option).
   I often make aliases for myself so that my primary address is not
   given out; if the alias gets out, I know who to blame.  Unfortunately,
   a reply to such a message would normally use the primary address
   without this patch.  A warning is displayed when this is going to
   happen so that it can be modified with '~h'.

6) CC and BCC lists:
   Allow '-c' and '-b' to accept white-space or ',' delimited lists.
   Currently, a white-space delimited list of addresses work, but a
   list of aliases will not get expanded.  For example, currently:

	mail -c "foo bar" christos

   will fail to send mail to 'foo' and 'bar' if these are mail aliases
   (in ~/.mailrc); sendmail aliases (in /etc/aliases) do work.

7) pipe command:
   This pipes the current message into a shell command.  I use this for
   quick decoding of uuencoded mail, but I can imagine it might be
   useful for decrypting encrypted mail, too.

8) show command:
   This command takes a list of variables and shows their values.  It
   is probably stupid as the 'set' command without any argument
   displays all variable values.  Of course, if there are a lot of
   variables you have to sift through the list for the one(s) you want.
