-;; Tree filtering
-
-;; A tree-filtering predicate is a function that receives a tree, and returns
-;; either #t/#f to include or exclude it, or it can return a function to be
-;; applied on its sub-trees.  This setup makes it possible to minimize the
-;; filtering work that is needed (compared to the old code that would compare
-;; full paths).  `tree-filter' takes such a predicate and returns a tree with
-;; filtered subtrees, so the smallest result is the empty root.
-
-;; Turns a byte string with globbing into a regexp string.  "*" turns to ".*",
-;; "?" turns to ".", "[...]" ranges are used as is, "{...|...}" turns to
-;; "(?:...|...)", backslash escapes as usual.  If the glob is "*", "*/", "**",
-;; or "**/", a corresponding symbol is returned; and if the glob is all
-;; literal, a byte string is returned.  No special treatment of "/"s, since
-;; these are used against path elements.  Note that this is applied on each
-;; part of a glob string, so "{...|...}" should not have "/"s in them.
