Import of RT #314

-------------------------------
I often wish 'What now?' prompt for many darcs commands included
'look for an item that matches a string I am going to type'.

An example session with a version of darcs that does not exist
on my machine with the feature I wish:

- In hunk selection interface of "darcs record", look for a
hunk that have a given string as substring; skip to it
without changing the action selection for the item currently
being asked about. '/' goes forwards, '?' goes backwards:

$ darcs record --ask-deps
hunk ./file 2
-primero change
+first change
Shall I record this patch? (1/350) [ynWsfqadjk/?], or h for help: /
Enter a string to look for (going forward): import
hunk ./file 230
-note so important line
+not so important line
Shall I record this patch? (224/350) [ynWsfqadjk/?], or h for help: y
hunk ./file 231
+some other change
Shall I record this patch? (225/350) [ynWsfqadjk/?], or h for help: ?
Enter a string to look for (going backward): primero
hunk ./file 2
-primero change
+first change
Shall I record this patch? (1/350) [ynWsfqadjk/?], or h for help:
...

- In patch selection interface of "darcs record --ask-deps",
look for a patch that have a given string as substring of its
name or comments; skip to it without changing the action
selection for the item currently being asked about. '/' goes
forwards, '?' goes backwards:

Sat Apr 2 08:55:05 PST 2005 junkio
* foo
Shall I depend on this patch? (1/320) [ynWvxqadjk/?], or h for help: /
Enter a string to look for (going forward): tripe ration

Fri Apr 1 12:30:59 PST 2004 junkio
* Double weight of tripe ration to balance the game difficulty
Shall I depend on this patch? (223/320) [ynWvxqadjk], or ? for help: y
...

I have also found myself looking for the "/" (search) option in patch selection
lists.

+1 that would be a nice feature. however, implementing it means to delve
into Darcs.UI.SelectChanges which is... challenging.
