I am having a problem either with v.out.ascii or v.digit. Using v.digit,
I edited a vector file (TIGER roads) to remove most of the lines contained in
it. The altered file is correctly displayed by d.vect and v.support seems
to recognize the reduction in lines, but v.out.ascii produces a dig_ascii
file with all of the lines from the original file. No dig_att file is produced.
What is the problem here?

In info.grass.user you write:

GO into GRASS and do a g.manual on the command 'v.clean'. I believe
your answer is there. You can run v.clean on the original file or
write a script on the dig_ascii file to remove all the lines that
begin with a small 'l' for linear areas, or a small 'a' for areal
areas. (Do a more on one of the files to see what I mean) I
recommend the former approach.
Gee I wish my problems with GRASS were as easily solved......
