GNU a2ps 4.14 + GNU wdiff 1.2.1 problem

$ cat t1
1 2 3 4
 $ cat t2
1 3 4
$ wdiff t1 t2
1 [-2-] 3 4
$ wdiff t1 t2 | a2ps --prologue=ul -Ewdiff -o 123.ps
[stdin (wdiff): 1 page on 1 sheet]
[Total: 1 page on 1 sheet] saved into the file `123.ps'
Content of 123.ps: "1 [-2-] 3 4"

However
$ wdiff -w "[wd-" -x "-wd]" t1 t2 | a2ps --prologue=ul -Ewdiff -o 123.ps
works. Content of 123.ps "1 _2_ 3 4"

It seems like the optional sequences in wdiff.ssh are not interpreted.

Cheers,

Christoph
