Well, it's the expectation that they have to press End/Ctrl-E before
extending the pattern. That will still work, the Ctrl-E will be just

Yes, I consider that a feature, despite I dislike it. It seems quite
common, at least mutt uses that feature, too.

Yep, I'm just experienced with the mini-buffer input and it behaves
there as described.

The idea behind that is probably the following:
Typing "/somesearchpattern<Enter>" should just work.
So if you type any printable character, the previous string is
discarded. But if start to edit it, i.e. press Backspace, cursor keys
or End, you can edit it.

Hrm, there it's mostly about not seeing the whole contents and not
about where to start to edit. And I'd rather would like to see the end
than the beginning, because usually these kind of strings get
developed recursively by adding stuff at the end. So if I only see the
beginning, it's unclear at which iteration I am.
But then again, I do agree that for the specific case of grouping,
this is probably different. I though consider it a special case as
that's a thing you edit very seldom compared to e.g. searching or
I'd say we should stay consistent with what people are used to from
other tools. And the current behaviour is unknown to me anywhere else.
Since aptitude refers to mutt for its design patterns in some places,
we could use mutt as pattern again:
* Start at the end
* Delete current contents upon typing the first printable character
Then again, vim and less start with a cleared search field and you
have to press cursor-up to get the previous search item.
So I'd be ok with both of these behaviour patterns. I'd refer in the
changelog to the application from which the pattern has been taken as
an argument for consistency. (And then someone will refer to the other
tool in a bug report, sure... ;-)

While I clearly agree and starting at the end, I'm unsure about the
automatic delete on typing. I assume I probably would prefer the text
to not be deleted automatically as I'm a mutt user, but not a vim
user, but I probably can only tell if I was able to compare it.

I nevertheless disagree at this point.
