'forward-comment' bug [Was: vhdl-mode bug?]

Hi, thank you for writing vhdl-mode, a very usefool tool. However, there is one annoying feature which is presumably a bug. When I use three hyphens to start a comment (this happens to be my personal convention) the indentation is faulty in the following lines. Here is my vhdl file: library IEEE; use IEEE.Std_Logic_1164.all; entity mips4kep is port (cmd: in integer; eb_avalid: out std_logic; eb_write: out std_logic; eb_a: out std_logic_vector (29 downto 0); eb_rdata: in std_logic_vector (31 downto 0); eb_wdata: out std_logic_vector (31 downto 0) ); end; -- fmi -- architecture fmi of mips4kep is attribute Foreign of fmi:architecture is "libfmi:mips4kep"; begin end fmi; In this form, indentation works. But if I write the comment as --- fmi -- things go wrong starting with line "architecture fmi of mips4kep is". To kreis this ein I switched on vhdl-echo-syntactic-information-p: -- fmi -- syntax: ((comment) (statement . 47)), indent= -1000 architecture fmi of mips4kep is syntax: ((statement . 47)), indent= 0 --- fmi -- syntax: ((comment) (statement . 47)), indent= -1000 architecture fmi of mips4kep is syntax: ((statement-cont . 347)), indent= 4 So, "architecture.." is indented by 4 if the comment starts with "---". I tried looking into the lisp, but I don't think I would be able to find the reason myself. Thanks for any help, Michael
