Make removecase() handle dirs as well as files through the use of a new
static delfiles_and_or_dirs() function which is basically delfiles()
with an option to remove() dirs too.
delfiles() simply calls this function now.

- Don't allow ? or * in the path
- Various bug-fixes

that exist.  Fix to delfiles() to delete from cwd if inpath is a zero-length
string.

use dest file as filename from editor.inf if subject is blank.

Sysops, rename all .pla files to .plan
Dance little SysOps dance!  BWA HA HA!

single function.
* editfile() now modifies a temporary copy of the file which solves 2 problems:
A. editors restricted to the temp dir (e.g. PICO) can now be used to edit other
    files (e.g. sig files)
B. DOS editors can now be used to edit files with long filenames
    (e.g. .plan files)

(not user-modifyable) - used for "New User Validation" e-mail.

- returns true/false if the user's terminal supports all the passed flags
- returns the supported flags if no flags are passed for comparison
- automatically uses the auto-terminal-type flags if no user is logged-on

in the if() - no functional change.

(sys_status&SS_USERON)

- can now modify the message subject/title, anon/non-anon toggle not supported.

This isn't actually usefull as of yet.

This doesn't currently actually accomplish anything, but a quick look shows
that it *could* be done by having writemsg() re-read it and update the
title as appropriate.  Currently, writemsg is always passed a modifyable
title parameter with a max length as follows:

bulkmail.cpp:  70
email.cpp:     70
fido.cpp:     127
netmail.cpp:  255 (in ::inetmail())
netmail.cpp:  127 (in ::qnetmail())
postmsg.cpp:   70

So, if editor.inf was re-read and, if the subject has changed, truncate it
to 70 chars and place the result in the title parameter, it should Just Work.

edited and just show the filename as the header.

defaults to false.

with the "maxdesclength" value in the ctrl/rss.ini file.

Stick with .pla all the time.

SYSOPS: Rename any data/user/*.plan to *.pla
(Or don't, nobody knows about ;plan anyways)

.pla in case of DOS editor usage for creation.

When QUOTES.TXT exists, use it as the quoter data and use the passed filename
ONLY as the file to save as.
When QUOTES.TXT does NOT exist, there is no quoter data, the passed filename
is both the input and output of the edited message.

If the filename parameter ents with (case-insensitive) "quotes.txt" or
"input.msg", the test should be handled by the quoter.  If not, the text
should be loaded as the message text.

This allows the ;edit function to work "perfectly" while not mucking up the
quoting stuff.

Fix bug when quoting last line of quote text.
