Normally, it would be more concise to use the more declarative name.
"en_8k" tells, how many terms we find in this wordlist. But as the
wordlist names are used in the CLI and users will normally simply
look for a wordlist in their language, it can help to keep the name
of the "default" list for each language short.

We pick the 8K lists for "default" (and not the "original" 6^5
lists), because we assume that normally people will use diceware
without dice. Also most other sources of randomness will most
probably work on a 2^x basis rather than in 6^x (and therefore
have better use for 8k lists over other ones).

Make sure that config file values are really considered by
handle_options().

With the new config module in place we must make sure, that any user
maintained .diceware.ini files do not interfere with tests.

The fixture sets $HOME for all tests automatically.

This test name was a duplicate, in effect overwriting the other test.

We also have to check the "True" case to make the test relevant.

We have to check for boolean before int, because int is also
a valid boolean.

By default we should read config files in user
homes.

We can build a sensible list of config file locations on-the-fly.

Right now we consider a file ".diceware" in the users home as
only valid place for a diceware config file.

when looking for valid wordlists.

Only return path if it exists and is valid.

Activates the -w option. Turns out we still have to fix
`get_wordlist_path` at it assumes that wordlists all end in
``.txt`` (which is not true).

We have to try hard to create a string accepted by all supported
Python versions.

Add test case that provides a file descriptor with broken seek(). We
must expect "broken" seek() methods for instance with sys.stdin.

Use conftest module for fixtures we need in several test modules.

We want to have such functionality be aggregated in a class.

Also in tests.

For wordlists we require a certain filename format. This is
described by a regular expression we introduce hereby.

This function provides pure WordList functionality and should be
part of this class therefore.

The functionality is replaced by the WordList class.

We do not support closing file descriptors automatically with
WordList. But (beside the fact that WordList instances require less
memory), we support reading a wordlist several times.
