<pre>Source file is:
% cat $FILE
#ifdef SOMETHING
#include <whatever>
#endif
Parse and save the tokens/skipping ranges:
% ./c-index-test -test-annotate-tokens=$FILE:1:1:4:1 $FILE > /tmp/1
Reparse and do the same:
% CINDEXTEST_EDITING=1 ./c-index-test -test-annotate-tokens=$FILE:1:1:4:1
$FILE > /tmp/2
Compare:
% diff -u /tmp/{1,2}
