Peter Eisentraut 6ae268cf28 Improve prep_buildtree ... When prep_buildtree is used to prepare a build tree when the source directory already contains another build tree, then it will produce the directory structure of the first build tree in the second one. For example, if there is postgresql/ postgresql/build1/ and a new build tree postgresql/build2/ is prepared, then this will produce postgresql/build2/build1/ because it just copies all subdirectories of the source tree. This is not harmful, but it's pretty stupid and can be confusing, and it slows down prep_buildtree when there are many build trees. When prep_buildtree was first created, it was more common for the build tree to be outside the source tree, in which case this is not a problem. But now with the arrival of meson, it appears to be more common (and also the way it is documented in the PostgreSQL documentation) to have the build tree inside the source tree. (To be clear: This change does not affect meson at all. But it would be an issue for example if you have a meson build tree and a configure build tree under the same source tree.) To fix this, change the "find" command to process only those top-level directories that we know about (namely config, contrib, doc, src). (I alternatively looked for ways to ignore directories that looked like build directories, but that seemed extremely complicated.) With that, we can also remove the code that ignores directories related to source-control management. In passing, also remove the workaround for handling prebuilt docs, since that has been obsolete since commit 54fac0e505.
