web/**/.htaccess: When there is no external redirect for the directory without the trailing /, instead auto-add the trailing / to ensure mod_autoindex relative links work properly. This must be done manually because the top-level .htaccess will not auto-add the trailing / if the dir has an .htaccess file (to allow the custom external redirects). There are actually only two .htaccess files that this applies to (web/.phpPgAdmin/.htaccess, .phpMyAdmin/.htaccess), indicating that dirs which have any kind of virtual paths (redirects) almost always have a "root" redirect when there is no specific subpath. This root redirect is intended to link to the datasource's own index of its available resources, e.g. the list of tables for a database source.

removed web/aggregators/.htaccess because it was only there to auto-add the trailing /, but this is now done by web/.htaccess

bugfix: web/.htaccess: auto-add trailing /: %{LA-F:REQUEST_FILENAME} lookaheads don't work, because they do not show the externally redirected URL, so we need to use an alternate mechanism instead, which just assumes that any dir containing an .htaccess file may contain a redirect and ignores just those dirs (subdirs are not ignored and will receive a trailing / as expected). To create the trailing / effect when you have a .htaccess without an external redirect, you need to manually tell it to correct the path for just that dir without the / (i.e. match ^/ , because a trailing / causes mod_rewrite to use an absolute filesystem path instead).

web/.htaccess: moved auto-add trailing / to after don't rewrite existing dirs, so that the path will automatically not be rewritten if it contains a trailing / and is a dir

web/.htaccess: don't rewrite existing paths: only prevent existing dirs with trailing / from being rewritten, because dirs without trailing / may be redirected

removed web/**/.htaccess whose only purpose was to auto-add the trailing / (which is now handled by the top-level .htaccess)

web/**/.htaccess: removed no longer needed auto-add of trailing / , which is now implemented for all dirs by the top-level .htaccess

web/.htaccess: auto-add trailing / if not external redirect: added test if `%{REQUEST_FILENAME} -d` in addition to checking %{LA-F:REQUEST_FILENAME}, because there are some cases (e.g. subdirs that are symlinked outside the DOCUMENT_ROOT) where LA-F:REQUEST_FILENAME for some reason appends /home to the REQUEST_FILENAME, but the current REQUEST_FILENAME is fortunately already a dir and can be checked directly

web/.htaccess: auto-add trailing / if not external redirect: removed no longer applicable comment that dir without trailing / is provided as an absolute filesystem path, because this is only true in inner .htaccess files for their top-level dirs

bugfix: web/.htaccess: auto-add trailing / if not external redirect: match any path that does not end in / (and satisfies the -d lookahead), rather than only absolute filesystem paths, which are only applicable in inner .htaccess files (and even then only for the outermost dir they control) but not in the top-level .htaccess file. Note that the inner .htaccess files can still use ^/ to match their own dir, just not their subdirs, without a trailing / .
