[Groff] pic does not work any longer

[Nicola Bernardini]

Dear Friends,

I use a lot pic as an algorithmic drawing language.
I am having problems with the latest CVS version of pic (tagged 1.16).
A very (very) simple pic script like this one:

        .PS
        scale=2.54
        .PE

does not get groked any longer by the pic preprocessor. It says:

./pic:/usr/local/user/nicb/tr/tmp/test.pic:2: parse error before `='
./pic:/usr/local/user/nicb/tr/tmp/test.pic:2: giving up on this picture
.lf 1 /usr/local/user/nicb/tr/tmp/test.pic
.lf 1
.lf 4

The version right before this one is groff-20000311 and it works as usual.
A diff -BbNu between the two versions gives:

I cannot make head of tails out of this, so I restored the old version
of pic (thanks god we have CVS!) - but I want to submit this to the list...

Thanks a lot

Nicola
