Looks like the .lint command has been in since 3.16.0, but this is my first
time noticing it and trying it out. I ran the .lint fkey-indexes on one of my
larger databases where I had thought I had indexed all the foreign keys ok, and
it spat out a giant swath of text, basically for every foreign key. I'm pretty
sure there's a bug in there triggered by collations.
Thanks for reporting this. Should now be fixed here:

Dan.
I'm also curious as to why it's putting identifiers in single ' quotes.
Here's a simplified example:
SQLite version 3.18.0 2017-03-28 18:48:43
Enter ".help" for usage hints.
Connected to a transient in-memory database.
Use ".open FILENAME" to reopen on a persistent database.
sqlite> create table a (id integer primary key);

Usage lint sub-command ?switches...?
Where sub-commands are:
fkey-indexes
sqlite> .lint fkey-indexes
CREATE INDEX 'b_b' ON 'b'('b'); --> a(id)
sqlite> create index idx_b on b (b);
