For decades just %! has been the "magic number" for Postscript files
and Postscript data streams.
Any additional data after the %! simply specifies additional
information about the Postscript code
contained in the file and is not required.
It is TeXshop, with its %!TEX, that is at fault. This is not a "magic
number" used to identify
a type of file. It is a TeXShop hack attempting to pass various
parameters to TeXShop
from source files and is incompatible with the use of magic numbers.
The developers of TeXShop really need to change %!TEX to something
else, %%!TEX has been
suggested on this list. Of course, this would cause backward
compatibility issues for some
TeXShop users. Those affected should not blame anyone but the
developers of TeXShop who
did not consider all of the ramifications of using %!TEX.
TeXShop is not the new gold standard and it is arrogant to suggest that
rest of the world should conform to or even recognize TeXShop hacks.
