BUG: ncdu 2.6 incorrectly outputs a root item with prev=0. The root item is
not supposed to be part of a directory and this field is properly absent in
later versions.

Testing
: If you're implementing a custom writer for this format, make sure to check
out the
[ncdubinexp.pl](https://code.blicky.net/yorhel/ncdu/src/ncdubinexp.pl)
script in the git repository. Ncdu only reads the parts of a file that it
actually needs, so passing a file to ncdu is no guarantee that it is
well-formed. The ncdubinexp.pl script is more thorough in validating file
correctness but misses a few invariants that ncdu does check for, so
the best way to verify a file is to run both:
out the 'validate' subcommand of
[ncdutils](https://code.blicky.net/yorhel/ncdutils). Ncdu only reads the
parts of a file that it actually needs, so passing a file to ncdu is no
guarantee that it is well-formed. ncdutils is more thorough:
```
ncdu -o/dev/null -f file.ncdu # Read entire tree and export to /dev/null
ncdubinfmt.pl <file.ncdu # Read and verify the entire file
ncdutils validate file.ncdu
```
Passing `--list-blocks` and `--list-items` may also be useful for
diagnostics.
