[TYPO3-bugs] RFC: pi_openAtagHrefInJSwindow() applies htmlspecialchars() twice

[Michael Stucki]

This is a SVN patch request.

Problem:
The input string for pi_openAtagHrefInJSwindow() needs to be an complete <a
href="..."> element, so it is clear that this must have htmlspecialchars()
applied. However, when sending out the resulting JavaScript link, the whole
content is sent through htmlspecialchars() again.

Solution:
I have removed the htmlspecialchars() call around the full output string but
added two new ones for $winName and $winParams only.

Branches: TYPO3_4-0 and Trunk
