The English speller only knew the 1990s Moby word list plus a small
hard-coded EXTRA array, so everyday modern words (desktop, laptop,
download, upload, spreadsheet, database, screenshot, inbox, offline,
workplace…) were flagged. Inflection, doubled-consonant and prefix rules
also only looked stems up in Moby, so even supplemented words failed in
inflected forms (blogging, uploader).
- New supplement assets/spelling/en-extra.txt: ~220 lowercase base forms,
our own list (MIT OR Apache-2.0), replacing the EXTRA array.
- All stem lookups (inflections, doubled consonant, prefixes) consult the
dictionary and the supplement; suggestions include supplement words.
- Regression tests: common modern words and inflections accepted,
misspellings still flagged, "dekstop" suggests "desktop"; the list
stays sorted and lowercase.
