Who do I talk to to encourage the inclusion of this feature in dselect?
As a long time user and fan of debian and dselect, I was distressed
yesterday to discover that there wasn't an easy way to escape after
somehow accidently telling dselect that a large number of packages were
to be removed. My error was discovered during the "Install" phase.
If this is the wrong place for such questions, please let me know.

Package: dselect
Version: 1.10
Severity: wishlist
Tags: patch
I spent some time on IRC today talking to a user who had messed up his
selections very badly in dselect and who had then mistakenly hit Enter.
Having done so, he was having great difficulty getting back to a sane
state: what he really wanted to do was to revert to what was currently
installed on his system, since he knew that was sensible. He expressed a
desire to "just remove dselect's todo cache".
However, we both had great difficulty getting dselect back to this
state. Hitting +, -, and _ on headings does part of the work, but it
tends to throw up conflict resolution screens along the way, and since
the user's installed state had no conflicts he didn't really want to
wade through those. I later noticed the unhold function, but it doesn't
appear to work on the "All packages" heading, and in any case it's a
little obscure.
I felt that there really ought to be an easier way to do this, analogous
to the 'R', 'U', and 'D' keystrokes which are plainly visible in the
help screen as ways to get out of trouble. Here's a patch which
implements 'C', "Set all to Currently installed state"; the intent is
that, with the exception of any partially installed packages, pressing
'C' then Enter should always result in [I]nstall having nothing to do,
regardless of whether any contrary selections have been established
beforehand.
