[PATCH] Quote any special characters in org-make-target-link-regexp

[Lawrence Mitchell <wence@gmx.li>]

* lisp/org.el (org-make-target-link-regexp): regexp-quote target
before replacing whitespace.

Previously a radio link <<<...>>> would match all three-letter words
in the buffer.  The manual indicates the radio links are meant to
match literally (modulo whitespace differences), so we should
regexp-quote all the targets to avoid over-eager matching.
---
This problem bit me when writing up some notes on CUDA, which uses
<<<...>>> to indicate a function call from a CPU onto a GPU.  I think
this is the right fix, since I can't imagine a situation where you
would want <<<foo.bar>>> to match foo.bar, rather than foo\\.bar.
