Bug of excluding directories

[Jie Zhang]

Suppose directory first-dir contain two directories: d and d2. My 
modules file contains:
  exmodule -a !first-dir/d first-dir
then checking out the module 'exmodule' will not check out both d and d2.

I read the source code and found that we should use
  strcmp (name, dir_ign_list[i])
instead of
  strncmp (name, dir_ign_list[i], strlen (dir_ign_list[i])
in function ignore_directory(name) in file ignore.c.

Is this a bug or an intended character of cvs?
