Filter out packages which depend on libncurses5-dev or
libncursesw5-dev, since changing their dependencies is out of the scope
for this transition.  For instance, cwidget is listed as "partial" in
the tracker, and I think this is because libcwidget-dev depends on
libncursesw5-dev.

The trailing '$' is there to match cases like logol where there is a
hardcoded dependency on libncursesw5.

Indeed not, thanks for checking.  The line below is what I meant.

is_bad = .depends ~ /\b(lib32ncurses5|lib32ncursesw5|lib32tinfo5|lib64ncurses5|lib64tinfo5|libncurses5|libncursesw5|libtinfo5|libtinfo5\-udeb)([^-]|$)/ & ! .package ~ /\b(libncursesw5|libncurses5)\b/;

Pardon my ignorance, but this is only the second time in my life where I
worked^Wstruggled with ben files.  And "ben monitor" only gives a list
of affected packages, I can't really check what is "good" or "bad" wrt
the state of the archive. :-(
