Compatible with autocomplete source function

[jordi-pujol-cayon]

Call accentFolding.fold at $.ui.autocomplete.filter() and leaving autocomplete.source as original.
Works with the three types of source: array of values, function or url-string.
Tested with "multiple" jquery-ui autocomplete example. https://jqueryui.com/autocomplete/#multiple

What are you trying to accomplish with this change?

[jordi-pujol-cayon]

With this change the extension does the same than before but extends the usage to source function calls.

I want a multiple selection box as seen in autocomplete example [https://jqueryui.com/autocomplete/#multiple] The autocomplete source must be defined at initialization as a function but the current accentFolding extension does not work because of the isArray check.
So I have moved the accentFolding.fold call outside of the source function and redefine $.ui.autocomplete.filter; now does folding at every filter search.

Of course I can mix the multiple example with folding example in a new source function and ignoring the extension, but doing this he source function definition becomes a matter for every autocomplete instance.

[scottgonzalez]

$.ui.autocomplete.filter is only used for array sources, so how is this possibly doing what you want?

[scottgonzalez]

Oh, I see, because the remote example is using the filter directly.

Can you clean up the code to actually follow the existing style and indentation?

[jordi-pujol-cayon]

Done. Forgot to answer.
