+Subject: [PATCH] Make hunspell look in XDG_DATA_DIRS for dictionaries
+
+Some dictionaries may exist but only show up under XDG_DATA_DIRS. For
+instance, $HOME/.local/share/hunspell could contain some dictionaries.
+
+This patch adds each directory in the hunspell subdir of each
+XDG_DATA_DIRS to the lookup path.
+
+Upstream pr is available at: https://github.com/hunspell/hunspell/pull/637
