ignore blank Pointer items on save

Ticket

ignore blank Pointer items on save+status

ignore blank Pointer items on save+priority

ignore blank Pointer items on save+tag

ignore blank Pointer items on save+commit

pattern: people often add a new item to Pointers just to add one, so the first one is saved as blank

Actually, it's more of a rendering issue, caused by extra newlines. Quickest solution was to fix the rendering (just added a "+" to the regexp)

Edit and save this:

replaced this old solution:

If there are Pointer items that are blank, don't even save them into the database.
