handlers to set flags only (with exception for sigquit(),
which still seems to call some non-reentrant functions on
its way to _exit(2).) That must eliminate the possibility
of catching SIGSEGV from following non-reentrant paths from
signal handlers.

Discussed with: nik, -audit
preventing anyone from downloading files. In conjunction with -A, and some
appropriate file permissions, this lets you create an anonymous FTP drop
box for people to upload files to.
The more obvious "-w" flag is already taken by NetBSD's ftpd. "-o" was
available as an option letter in all three BSDs.
Limit the "pathname" glob to one item, as that is what all users of it
are expecting, except for LIST.
Always glob, instead of when the first character is a ~. For example,
if you had directories ~/x1, and ~/x2, then "cwd x[1]" would fail, but
"cwd ~/x[1]" would work since it was globbed due to the ~ character.
Also, "cwd ~/x[12]" used to arbitarily work as it used the first
expansion (ie: x1) without an error. Make it return '550 ambiguous'
instead of '550 not found' so that the user can see the difference.
For LIST, just use the user supplied string as the popen does the glob.

This allows you to determine if the file on the other side is the same
as the one you have without transferring the entire file to compare.
Needless to say, if the server end lies to you this check doesn't work,
but on the other hand, if it lies to you about the files checksum,
what can you trust from it ?
plain 0 should be used. This happens to work because we #define
NULL to 0, but is stylistically wrong and can cause problems
for people trying to port bits of code to other environments.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
Document the new -R (relax paranoia) option.
From NetBSD/Lite2: code and man page cleanups, Kerberos IV hooks
(relax, we're still exportable), and /etc/ftpchroot feature for
semi-anonymous accounts
or addresses other than the requestor's address. This violates the FTP
protocol (hmm...as I write this, I'm going to change this to a run-time var.)
Require login before PASV and RNTO commands.
Close unused PASV ports so they don't hang around forever.
Do not allow file overwrites via rename or STOR when anonymous
(suspenders).
Clean up buffer utilization.
My code, but heavily inspired by Hobbit's changes to wu-ftpd as pointed out
by Mike Prettejohn and Kit Knox.
