Uh, you people are joking, right? It is not a bug in TeXshop if
Emacs' magic-mode-alist goes out of control and calls everything

Since I don't seem too good at explaining what appears as common sense
to me, I'll fix the magic expression myself to "#!PS". That's still a
less drastic change than removing it altogether, and most people seem
to agree that the latter option would be quite feasible.
This won't catch "#!\n" which seems to be used in some hand-crafted PS
files, but then the handcrafted files (vasarely.ps, for example)
should be discernible by file extension, and one would have to
actually use some generic line-ending recognizer instead of "\n",
anyway, since PostScript has no fixed line-ending convention.
If others find they want even the "#!PS" gone (which I don't really
see as a problem), or add some form of "#!lineend", feel free to
discuss and fix.
