After some more investigation, i think it has to do with the
buffer/file not being erased before the ascii is rendered. It works
for html export, it does not for txt export. Not sure why this should
be, the code i looked at seems to try to clear the buffer.

only a selection. I use 5 groups of tags for active projects.
The first group just contains @proj - the active projcet tag. This  is
used with the second group <@home|@work> which are inherited by all of
the active projects in the two huge org files i use for home and work.
The last three groups are generally @<physical context group> ,
<activity context group>@, and <possible duration context>@ which i
combine depending on the task.

I did think of a regular expression, the docs mention its possible,and
give a small example, but i  couldn't get it to do what i wanted
straight away, and didn't want to spend the time figuring it out. I
considered suggesting a group name/selection type, but it seemed a bit
fiddly.
