+/// Adds a highlight to buffer.
+///
+/// This can be used for plugins which dynamically generate highlights to a
+/// buffer (like a semantic highlighter or linter). The function adds a single
+/// highlight to a buffer. Unlike matchaddpos() highlights follow changes to
+/// line numbering (as lines are inserted/removed above the highlighted line),
+/// like signs and marks do.
+///
+/// "src_id" is useful for batch deletion/updating of a set of highlights. When
+/// called with src_id = 0, an unique source id is generated and returned.
+/// Succesive calls can pass in it as "src_id" to add new highlights to the same
+/// source group. All highlights in the same group can then be cleared with
+/// buffer_clear_highlight. If the highlight never will be manually deleted
+/// pass in -1 for "src_id".
+///
+/// If "hl_group" is the empty string no highlight is added, but a new src_id
+/// is still returned. This is useful for an external plugin to synchrounously
+/// request an unique src_id at initialization, and later asynchronously add and
