As I said, in most cases it will swallow that line, even when (IMHO) it's 
not supposed to, like in the former case you describe (the way it is 
essentially means that you can't have a file that begins with #, no biggy, 
but still weird).  In one exception (when it can't figure out the filepath 
from the environment and reverts to argv0), it doesn't check for this # 
line, and thus, will spit it out as regular output if it's there (look at 
cgi_main.c, around line 720).

Generally, I think the right solution would be making only
./foo.php (after chmod +x)
work.  php -q foo.php shouldn't treat foo.php as if it was a shell script.

This solution has two major drawbacks:
- It might break people's setups.
- It's not very easy (and perhaps not possible) to detect in which mode we 
are.  We determine whether we're in CGI or not by looking at the 
environment variables, but those will be around even if we're running as an 
#! executable, as long as we're running as a CGI...

Unless someone has a bright idea as to how to deal with it, I think the 
best thing to do would be fixing the inconsistent case to be consistent 
with the other cases, even if this whole behavior is a bit wrong...
