"Add tag" popup overwrites existing textbox content

[htoomik]

Steps to reproduce:
I am entering tags in the Post tags section of the Edit post page and have entered multiple tags in the textbox.
I pause in the middle of a word.
A little box pops up below the textbox, suggesting existing tags that match what I have typed.
I click the tag in the popup.

Expected behaviour: the tag I clicked is added to the list, overwriting everything after the last comma in the textbox.
Actual behaviour: the tag I clicked overwrites everything I had already typed.

Example: I have typed "weather,winter,snow,sw". The popup comes up suggesting "sweden".
Expected textbox content: "weather,winter,snow,sweden".
Actual textbox content: "sweden".

Quick Note, This doesnt occur if you use the Delimiter ", " instead of simply ",".

Changing the .suggest() js calls to use "," as the MultiDelimiter doesnt seem to help this case however. It appears that this is a bug within jquery.suggest to me.

I tested using Opera 10.10, incase it makes a difference.

I'm for a wontfix.
Suggest can only handle one delimiter, it would be find if it can support ", " and "," but in this case it's ", ". If we use "," as delimiter we get problemes with the old delimiter.

In 12152.patch we can handle now both delimiter, default is "," but you can use ", " too.

(In [14387]) Handle ", " and "," in non-hierarchical term suggestion. Props ocean90. Fixes #12152
