I would like to add that only a single diff hunk is generated for the following script variant
of the semantic patch language (as it would usually be expected for the mentioned software component).

@replacement@
@@
-fprintf
+putchar
 (
-stdout, "\n"
+'\n'
 )

How can the generation of duplicate difference output be avoided here
for other SmPL script variations?
