…lude <Python.h>' in the .c file
This is mainly just for namespacing purposes and to set a pattern for future helper lib functions.
In future I may move most of the code out into an autoload file, but in the meantime I want all the code tidy and in one place for the next release
Previously we were blowing away highlights that were added by other plugins via matchadd(). To prevent this we now track all the ids of the highlights groups we add and remove them explicitly with matchdelete().
…rgument to force callback call Normally if location item has "col" item, syntastic#HighlightErrors() handle it without callback call for performance reason. But sometimes it's necessary to handle all items with callback (like in new vala syntax checker), so third optional bool arg is added to the function. If this argument exists and has true value, then callback function is called on *all* location items, no matter is they have "col" element or not.
