Inconsistent spacing (space-vs-tab doesn't matter in this particular 
context, but it looks weird to use both)

Your use of xargs as a reformatter is interesting ;) Could also be spelled:

$(echo $lang_plugins $non_lang_plugins | tr -s ' \t\n' ' ' | sort -u | 
tr ' ' '\n')"

but that's longer to type, so your version is fine.
