[GRASS-dev] RE: [GRASS-user] g.mlist newline separator request

[Patton, Eric]

Well, as no one seems to have had an objection or comment, and I can confirm that it does indeed work, would it be possible for someone to commit Martin's patch to CVS?

Thanks,

~ Eric.

Hi,

this patch should fix it.

But I am not sure whether to commit it to CVS. Patch seems to be
"ugly" for me, moreover I am not sure why printf fn was used in the
script (?)
