So it does, but only if there is no active match nor keyword at the
cursor. What I should have said is that synIDattr() (or maybe I should
say synID()) reports only the "innermost" syntax item at the cursor.
For example,
:help r
:normal 6j0
:echo synIDattr(synID(line("."), col("."), 1), "name")
reports helpLesdBlank but does not mention that this syn-match (defined
with "contained") is inside a helpExample syn-region. (Verify this by
moving the cursor to the first non-blank on the lins.)
In brief, synID() *sometimes* reports the current syn-region, and I
do not think this is good enough for David Brown's purposes.
