#' Absolute path linter
#'
#' Check that no absolute paths are used (e.g. "/var", "C:\\System", "~/docs").
#'
#' @param lax Less stringent linting, leading to fewer false positives.
#' If `TRUE`, only lint path strings, which
#'
#' * contain at least two path elements, with one having at least two characters and
#' * contain only alphanumeric chars (including UTF-8), spaces, and win32-allowed punctuation
