Are the bounds of a SourceRange meant to be inclusive of whatever
source location is indicated by the 'end' value? I ask because I have
a cursor for the string literal "xyz" in a call like 'func("xyz", 1)'
and the range associated with this cursor is (5, 10), if we say 'f' is
at 0. Index 10 is the index of the ',' after the string literal. This
leads to the odd situation whereby calling clang_tokenize on the
source range generates two tokens. One for the string literal and one
for the trailing comma.
Is this expected behaviour?
