I could solve this finally by:

| diff --git a/data/php.m4 b/data/php.m4
| index 7095d8a..6ab2600 100644
| --- a/data/php.m4
| +++ b/data/php.m4
| @@ -262,7 +262,9 @@ m4_define([b4_lex_param_call],

| +m4_define([b4_param_call], [, m4_bpatsubst($1, [^.* ], [])])

As stated, I think this rather belongs in add_param ().

  But the more important point is that now the code generat-
ed doesn't need manual tweaking anymore, and therefore re-
gression tests are on the horizon :-).
