Yep:

andrew(at)emma:utils $ touch Gen_dummy_probes.sed
andrew(at)emma:utils $ touch ../../../src/Makefile.global
andrew(at)emma:utils $ make top_srcdir=../../.. Gen_dummy_probes.pl
perl -ni -e ' print; exit if /^\$0/;' Gen_dummy_probes.pl
s2p -f Gen_dummy_probes.sed  | sed -e 1,4d -e '/# #/d' -e '$d' >>
Gen_dummy_probes.pl
perltidy --profile=../../tools/pgindent/perltidyrc Gen_dummy_probes.pl
perl -pi -e '!$lb && ( /^\t+#/  || /^# prototypes/ ) && print qq{\n};'\
    -e '$lb = m/^\n/; ' Gen_dummy_probes.pl
andrew(at)emma:utils $ git diff
andrew(at)emma:utils $ perltidy --version
This is perltidy, v20170521
