Thanks for your bug report.  If I set completion-auto-select in emacs -Q, 
C-x C-f C TAB (or TAB TAB, depending on the value of 
completion-auto-select) in the Emacs repository behaves as expected. 
However, C-x C-f src/ TAB does not.  Is the latter case what you have in 
mind, or do I misunderstand what you mean?  If not, the attached patch 
should fix that bug.
