Right - this seems to be the opinion of several other contributors as well.

Eh - no good reason - and I am happy to change the option name if people
think that --lint is better.  I used -L as it was reminiscent of "lint"
(and "l" was already taken).  But I picked --enable-checks as this seemed
more obvious to me than --lint.  (My guess was that not all users will be
familiar with using the word 'lint' to mean 'check for errors'.  It is a
kind of niche term).
