Description:
------------
It would be really useful to be able to write single files that would run cleanly 
as *either* CGI or CLI scripts. 

At the moment, the closing '?>' tag will eat the trailing newline.

So, similarly, I'd like to request a way for the opening '<?' tag to eat the 
previous literal shebang line.

Test script:
---------------
#!/usr/bin/php
<?
if (php_sapi_name()== "cgi"){
   erase_previous_line()       <-- hypothetical function.
   echo "I am CGI<br>";
}else{
   echo "I am CLI\n";
}
?>

Expected result:
----------------
Exactly one line should be printed: 
  "I am CLI|CGI"

Actual result:
--------------
In CLI mode, this script cleanly prints:
  "I am CLI"
but in Apache mode, the script prints the first line literally:
  "#!/usr/bin/php
   I am CGI<br>"


It's relatively easy to work around this with a wrapper script, but I'd 
appreciate the elegance of having a single file that can operate in both modes.
Thank you for your time.
