I'm not sure I agree.  If you update the survey you're likely to want the
new legs to appear in the extended elevation by default, which points to
listing excluded legs or traverses in the fold file.  Also there are likely
to be far fewer legs excluded than included which means listing excluded
ones would be more compact and quicker to process.

I'm not sure it would be any clearer - besides the intention is that most
people would use the graphical editor anyhow.
