[Bug-wget] broken progressbar in 1.16

[Michael Shigorin]

        Hello,
please do pay attention to regression testing for innovative
bells and especially whistles as the "new and improved" progress
bar quickly becomes annoying if the filename is longer than the
part of the line before percent meter: the new code tries to
scroll it (this alone might be irritating to some including
myself) and for some cases fails to do that properly falling into
"spam out a new line every cycle" in xterm with an UTF-8 locale.

e.g.,

$ LANG=ru_RU.UTF-8 wget -c

while disabling l18n would result in most of the spam missing:

$ LANG=C wget -c

...but adding the "conversion" spam.

Guys, please do RCs or whatever to avoid brown paper bag effects
in products that were mature years ago.  I love you and thank for
your work but please please don't feel cool, people depend on wget.
