Until PG15, calling pgindent without arguments would process the whole
tree. Now you get
No files to process at ./src/tools/pgindent/pgindent line 372.
Is that intentional?
Also, pgperltidy accepts no arguments and always processes the whole
tree. It would be nice if there were a way to process individual files
or directories, like pgindent can.
Attached is a patch for this.
(It seems that it works ok to pass regular files (not directories) to
"find", but I'm not sure if it's portable.)
