# there's a bug in the regex Document::DATE_FILENAME_MATCHER:
# %r!^(?:.+/)*(\d{2,4}-\d{1,2}-\d{1,2})-(.*)(\.[^.]+)$!
# used by:
# jekyll/lib/jekyll/readers/post_reader.rb#read_posts
# which ultimately populates:
# site.posts.docs
#
# the original code's intention was to match:
# all files with a date in the name
# but it accidentally matches also:
# all files immediately within a directory whose name contains a date
#
# our plugin changes the regex, to:
# avoid false positive when directory name matches date regex

# Suppress warning messages.
