You forgot to properly quote the [a-z] range.  m4 strips away the [ and ]  
and leaves only 'a-z', which is not what you intended.  You need to use  
[[a-z]].  Also, the space before the 'd' in '! d' is non-portable.  That will  
cause an error in some sed programs.  You should eliminate the space and use  
'!d'.
