Chromium, like many other Debian programs, uses hunspell for spelling.
However, unlike most other apps that use hunspell directly or indirectly
(e.g. Firefox, Pidgin, LibreOffice), Chromium uses a custom personal word
list format, and hence can’t share a per-user word list. (The other programs
mentioned can simply have their user wordlist file symlinked to a single
file, e.g. ~/.hunspell_en_GB.)

Would it be possible to patch Chromium to integrate it better with Debian in
this respect?
