We have 4 inputs:
- u7z.simple.input
Simplest input: no abnormalities.
(One line has a filename with spaces in it.)
- u7z.missing-date.input
Date field is missing (see #2707).
- u7z.missing-size-and-date.input
Size field is missing, and in some rows the date is missing too (see #2707).
- u7z.complex.input
Downloaded from #2707. It's 'list.txt' plus three bottom lines from
'listing2.txt'. It demonstrates all the above: missing date, missing
uncompressed and compressed size.
Output files must be constant. Therefore in our '*.env_var' files we
define a command that sets missing dates to some fixed date (instead of
being the archive's date).
