Making auto-mode-alist override interpreter-mode-alist

[Francis Devereux]

Hi,

I have derived a mode from python-mode that has some settings for my  
company's Python coding style.  I want to use this mode (bright-python- 
mode) for .py files in certain directories but use the default python- 
mode for all other .py files.

I have the following in my auto-mode-alist:
(set-variable 'auto-mode-alist
          (append '(
...
            ("/Users/francis/Code/Bright/.*\\.py$" . bright-python- 
mode)
...
            ) auto-mode-alist))

This works for most files, but not for those whose first line is #!/ 
usr/bin/python.  They always open in python-mode, regardless of the  
directory that they are in.  I think that this is happening because  
interpreter-mode-alist is overriding auto-mode-alist.  Is there any  
way to make auto-mode-alist have priority over interpreter-mode-alist?

I don't really want to remove the python entry from interpreter-mode- 
alist because then Python scripts with a shebang whose names don't end  
in .py wouldn't open in python-mode.

Thanks,

Francis
