+Patch 7.1.215
+Problem: It is difficult to figure out what syntax items are nested at a
+ certain position.
+Solution: Add the synstack() function.

++ synstack({lnum}, {col}) *synstack()*
++ Return a |List|, which is the stack of syntax items at the
++ position {lnum} and {col} in the current window. Each item in
++ the List is an ID like what |synID()| returns.
++ The stack is the situation in between the character at "col"
++ and the next character. Note that a region of only one
++ character will not show up, it only exists inside that
++ character, not in between characters.
++ The first item in the List is the outer region, following are
++ items contained in that one. The last one is what |synID()|
++ returns, unless not the whole item is highlighted or it is a
++ transparent item.
++ This function is useful for debugging a syntax file.
++ Example that shows the syntax stack under the cursor: >
++ for id in synstack(line("."), col("."))
++ echo synIDattr(id, "name")
++ endfor
