problem with implicit space detection

[flagadajones]

Hi,
In EMF text 1.4.1 a rule like this :

ProgramModel ::=     "PROGRAM(" "NAME=" name[TEXT] "," "FILENAME=" filename[PATH_NAME] ")";

find a line like this

PROGRAM( NAME= TOTO, FILENAME=d:/klkkl )

in 1.4.2 with same rule my line is not found with error :

Syntax error on token " " Expected: "FILENAME=". 

it work if i changed my line like this :

PROGRAM( NAME= TOTO,FILENAME=d:/klkkl )    => remove whitespace before FILENAME
