JS's console.getkeys(). If no mode value is specified, K_UPPER is the default
behavior (same as before). *.getkeys() currently only recognizes the following
mode flags:
- K_UPPER
- K_NOECHO
- K_NOCRLF

K_NONE (0) is also a valid value.

MSVC had no problem with this. <sigh>

Use this in place of JS_GetPrivate() in native class methods that need the
class instance's private data pointer and will do bad things if that pointer
points to something other than what is expected. mcmlxxix (matt) discovered
that using Object.apply(), you can invoke class methods where the 'this'
instance is a different class. This would result in
"Internal Error: No Private Data." or a crash.
So now, gracefully detect this condition and report a meaningful error:
"'<class-name>' instance: No Private Data or Class Mismatch"

Also, important to note: if the method uses JS_THIS_OBJECT to get the JSObject*
to pass to JS_Get*Private, then it must do this *before* it calls JS_SET_RVAL.

From jsapi.h:
 * NB: there is an anti-dependency between JS_CALLEE and JS_SET_RVAL: native
 * methods that may inspect their callee must defer setting their return value
 * until after any such possible inspection. Otherwise the return value will be
 * inspected instead of the callee function object.

The js_crypt*.c files still need this treatment.

the 'keys' argument is optional. If no keys are specified (or NULL), then any/
all non-numeric keys are considered valid input and may be returned by this
function/method.

as well as the auxattr "Attach" when either FILEATTACH or MIMEATTACH is set
(requires an updated MsgAttr line in text.dat).

I know... this list of %s's was a bad idea to begin with, but oh well.

Set the current node action value *before* calling the scanposts_mod

the (never used) SMB_PRIORITY 32-bit hfield (0 = default/highest priority), to
a new fixed message header field (8-bit) following the X-Priority header field

Expanded codes will not *not* go beyond the terminal column width (minus 1).
If you need the old/wrap behavior, add a "-W" modifier to your @-code.
If a length value is specified with -W, it is ignored.

- MSG_TO, MSG_FROM, MSG_SUBJECT now reflect the header values passed

  actual stored (e.g. MIME-encoded) header values.

New codes:
- MSG_CC - reflect a message's CC list, if it has one
- DATETIMEZONE - combines DATETIME and TIMEZONE in one string

show_msghdr(), over-riding the values from the passed smbmsg_t. This is useful
for, say, displaying MIME-decoded values rather than the MIME-encoded versions
of the header fields that you often find in email today.

Copy the upvotes, downvotes, and total_votes to the smbmsg_t, replicating
what is done in sbbs_t::scanposts() - these are used by sbbs_t::show_msghdr()
so we need to copy them if we're going to be replicating that functionality
(showing up/down votes and score) in message headers shown with bbs.show_msg()
and bbs.show_msg_header().

bug but now appears because we are now (recently) actually storing the SMTP

This is a heap-allocated copy of the text from the message body, so it must be

US-ASCII.

The default is off (no stripping). Previously, Soft-CRs were always stripped,
but this behavior is now seen as an anachronism as CP437 char 141 is an
important non-English laguage character and used as such in FidoNet msgs.

For QuickBBS editors, the default will be the same as previous behavior: to
convert Soft-CRs to Hard-CRs (CRLFs).
For non-QuickBBS editors, the default will be to treat Soft-CRs as any other
valid printable character in the text ("Retain").
A 3rd option is available to strip Soft-CRs completely from the generated
message text.

Refer to the dubious get_msg_body() feature of dot-stuffing as that
("dot-stuffing") and not "rfc822-encoding" - because it isn't.
dot-stuffing is a requirment of SMTP (RFC*821) and NNTP, not RFC822 (oops).
