remove wish not possible when search contains parens

[hboetes]

zniavre noticed he could not remove the following wish:

autosearch = ['Every day people (feat. Proleter)'] 

I guess it has something to do with the parens.

Add Wish including parenthesis symbols is only possible from within the Wishlist dialog. However on testing this, it would seem that such items do not yield any results and no new Search Files Wish tab is ever created for them.

Usually in a normal search, symbols including parenthesis are stripped, which is why Remove Wish doesn't match the wish entry. However, it is possible to remove a Wish item from the Wishlist dialog, either with Remove Wish button in there or with Shift+Delete.

It makes me wonder if perhaps new Wishlist items should go through the symbol stripping procedure the same as new ordinary searches, or maybe it's better if they are stored as is but then stripped upon submitting each Wish search event (Edit: as is done with translate(self.translatepunctuation) but I don't know what unforeseen consequences of doing this might be).
