+/**
+ * Format an SQL query. This function behaves like sprintf(), except that
+ * all the normal conversions (like %s) will be properly escaped, and
+ * additional conversions are supported:
+ *
+ *   %nd, %ns, %nf
+ *     "Nullable" versions of %d, %s and %f. Will produce 'NULL' if the
+ *     argument is a strict null.
+ *
+ *   %=d, %=s, %=f
+ *     "Nullable Test" versions of %d, %s and %f. If you pass a value, you
+ *     get "= 3"; if you pass null, you get "IS NULL". For instance, this
+ *     will work properly if `hatID' is a nullable column and $hat is null.
+ *
+ *       qsprintf($conn, 'WHERE hatID %=d', $hat);
+ *
+ *   %Ld, %Ls, %Lf
+ *     "List" versions of %d, %s and %f. These are appropriate for use in
+ *     an "IN" clause. For example:
+ *
+ *       qsprintf($conn, 'WHERE hatID IN(%Ld)', $list_of_hats);
+ *
+ *   %T ("Table")
+ *     Escapes a table name.
+ *
+ *   %C, %LC
+ *     Escapes a column name or a list of column names.
+ *
+ *   %K ("Comment")
+ *     Escapes a comment.
+ *
+ *   %Q ("Query Fragment")
+ *     Injects a raw query fragment. Extremely dangerous! Not escaped!
+ *
+ *   %~ ("Substring")
+ *     Escapes a substring query for a LIKE (or NOT LIKE) clause. For example:
+ *
+ *       //  Find all rows with $search as a substing of `name`.
+ *       qsprintf($conn, 'WHERE name LIKE %~', $search);
+ *
+ *     See also %> and %<.
+ *
+ *   %> ("Prefix")
+ *     Escapes a prefix query for a LIKE clause. For example:
+ *
+ *       //  Find all rows where `name` starts with $prefix.
+ *       qsprintf($conn, 'WHERE name LIKE %>', $prefix);
+ *
+ *   %< ("Suffix")
+ *     Escapes a suffix query for a LIKE clause. For example:
+ *
+ *       //  Find all rows where `name` ends with $suffix.
+ *       qsprintf($conn, 'WHERE name LIKE %<', $suffix);
