[bug-inetutils] Recent changes to ftp.

[Mats Erik Andersson]

Dear all,

I have just pushed a series of patches that mainly touches 'ftp'.
The intention is to lift the artificial line length limit present
in the legacy code.

The old limit of 200 has now been replaced with a dynamic mechanism
for most parts, but there are still two spots with BUFSIZ as limit.
This is orfv the order 1024 for most systems, so some gain has been
achieved. However, this also means that putting very long paths in
"~/.netrc" will work with our "ftp", but will cause segfaults with
the system specific netkit-ftp, solaris-ftp, *BSD-ftp.

I welcome further triage of the new client. Beware, however, testing
needis to examine use cases of "ftp" with and without line editing;
normal commands and macro commands; machine specific text in "~/.netrc"
as well as rejected text in "~/.netrc". I found the hard way that
all these are relevant and they each depended on different parts
in the legacy code.

On the good side is the fact that my patch series removes six segfaults!

I am still working on the problems reported by Glenn Golden, found when
running Arch Linux. Defects which I cannot reproduce, but they are still
persistent for him, so need to be understood.

Best regards,
  Mats E A
