my _darcs/prefs/boring file has the following line:

(^|/)_darcs($|/)

and I am sure I didn't put that there (I never touch the boring file).

Just to be sure:

nimrod at midway:~/trees/test> darcs init
nimrod at midway:~/trees/test> mkdir sub
nimrod at midway:~/trees/test> cd sub/
nimrod at midway:~/trees/test/sub> ls
nimrod at midway:~/trees/test/sub> darcs init
nimrod at midway:~/trees/test/sub> cd ..
nimrod at midway:~/trees/test> ls
_darcs  sub
nimrod at midway:~/trees/test> darcs record --look-for-adds
Darcs needs to know what name (conventionally an email address) to use as the
patch author, e.g. 'Fred Bloggs <fred at bloggs.invalid>'.  If you provide one
now it will be stored in the file '_darcs/prefs/author' and used as a default
in the future.  To change your preferred author address, simply delete or edit
this file.

What is your email address? fred at bloggs.invalid
adddir ./sub
Shall I record this patch? (1/1) [ynWsfqadjk], or ? for help: y
What is the patch name? sub
Do you want to add a long comment? [yn] n
Finished recording patch 'sub'

or more closely to what Andrew is trying to do:

nimrod at midway:~/trees/test> mkdir sub
nimrod at midway:~/trees/test> cd sub
nimrod at midway:~/trees/test/sub> darcs init
nimrod at midway:~/trees/test/sub> darcs record
No changes!
nimrod at midway:~/trees/test/sub> cd ..
nimrod at midway:~/trees/test> ls
sub
nimrod at midway:~/trees/test> darcs init
nimrod at midway:~/trees/test> darcs record --look-for-adds
