-# golint fails to report many lint failures if it is only given a single file
-# to work on at a time, and it can't handle multiple packages at once, *and*
-# we can't exclude files from its checks, so for best results we need to give
-# it a whitelist of every file in every package that we want linted, per package.
-#
-# so lint + this golint func works like:
-# - iterate over all lintable dirs (outputs "./folder/")
-# - find .go files in a dir (via wildcard, so not recursively)
-# - filter to only files in LINT_SRC
-# - if it's not empty, run golint against the list
