The implicit fall through case label here is intended, so let us inform
that to gcc >= 7:
util/strfilter.c: In function 'strfilter_node__sprint':
util/strfilter.c:270:6: error: this statement may fall through
[-Werror=implicit-fallthrough=]
if (len < 0)
^
util/strfilter.c:272:2: note: here
case '!':
^~~~
cc1: all warnings being treated as errors
