darcs annotate fails when there are spaces in the file or directory name.  
Example:

$ touch "file name"
$ darcs add file\ name
$ darcs record
addfile ./file\32\name
Shall I record this change? (1/?)  [ynWsfqadjkc], or ? for help: y
What is the patch name? test2
Do you want to add a long comment? [yn]n
Finished recording patch 'test2'
$ darcs annotate file\ name

darcs failed:  There is no file or directory named 'file name'

It works when there are no spaces in the file or directory names.  (Maybe 
other special characters should be checked as well.)

Confirmed on 1.0.9rc1 here.  However, I was able to recover the
annotation this way:

$ darcs annotate test\\32\\file

it seems that special characters are not being escaped at the command-level.
