## Intent: Morph exclusion strings into command line arguments.
##   NOTE: Do not double-quote argument: -ignore-path "$(dir)"
##         Single quotes surrounding exclusion strings added in doc8/excl.mk
##         will become part of exclusion string and fail pattern matching.

## [TODO] - move lint-doc8-excl into doc8.ini (autogenerate)
