OK, based on this feedback, I have updated the pgindent README to use
these Perl indent instructions:
find . -name \*.pl -o -name \*.pm | xargs perltidy \
--backup-and-modify-in-place --opening-brace-on-new-line \
--vertical-tightness=2 --vertical-tightness-closing=2 \
--nospace-after-keyword=for --nospace-for-semicolon \
--add-whitespace --delete-old-whitespace --paren-tightness=2 \
--keep-old-blank-lines=2 --maximum-line-length=78 \
--entab-leading-whitespace=4 --output-line-ending=unix
Unless I hear otherwise, I will run this new command on the 9.2 and HEAD
Perl files.
