mboxShell

First stable release, with a config file that finally works

• The first stable release. From now on the command line and the config file follow Semantic Versioning (SemVer): anything that breaks them will only arrive in a new major version. 7 new tests (308 in total).
• New mboxshell config [path|show|defaults] command (#40). path says where the config file is and whether it exists yet; show prints it with a warning for each value it ignores; defaults prints every option with its default value as a commented file. It changes nothing and only writes to standard output, so redirecting defaults into a file gives you a starting point.
• Most config file options used to do nothing: only the log level, the theme and the two attachment options were read. default_sort, sort_order, date_format, layout, show_sidebar, max_cached_messages, csv_separator and cache_dir now work, and an invalid value falls back to its default with a warning instead of being silently ignored. On macOS the file is ~/Library/Application Support/mboxshell/config.toml, not ~/.config/mboxshell as the README said.

Exports that match their attachment folders

• export now takes --dirname dts|seq-no|seq-no0 and --seq-width N, like attachments and with the same defaults from the config file (#39). With seq-no, each EML, TXT or HTML file is named after its message's attachment folder — 0007.html goes with the folder 0007/ — so an exported email and its attachments are easy to pair up, and TXT and HTML exports also show that folder under the attachment list. dts, the default, keeps the usual names.
• In a mailbox that starts with a UTF-8 byte order mark (BOM), the first message was exported wrong (#38): its EML or Maildir file lost the subject, and export --format mbox wrote a duplicate separator in front of it. The BOM is now skipped, so the first message exports like any other. 7 new tests (301 in total).

No more crash when exporting accented names

• Fixes a crash when exporting messages whose subject or sender has an accented letter near the start (#37). The Windows reserved-name check added in v0.8.0 cut file names in the middle of a multi-byte character; it affected HTML, EML and text exports and attachment extraction on every platform.
