Here's a little ditty I cooked up once to do this.  (This is really non-perlish perl,
but it worked for all the cases I needed...8^)

#!/usr/local/bin/perl

#  provides name completion in a cd command.
#  Format:
#    alias cd 'chdir `compcd \!*`'
#  Then, you can:
#
#    cd NewPathName
#
#  The format of the NewPathName argument is the same as that of any
#  regular CD command, with the exception that the first '-' in ANY
#  filename is removed, and the filename is handed verbatim to chdir.
#  
#  So:  cd  /scr/ke/cd         Will change into the /scratch/kenc/cd 
#				directory, unless there's some ambiguity
#       cd  /scr/-kenc/cd      Will change into the /scratch/kenc/cd
#				directory specifically, and not perform
#				completion on the 'kenc' part.
