What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

wget https://raw.githubusercontent.com/bazelbuild/bazel/refs/tags/8.0.0/src/main/protobuf/bazel_flags.proto
bazel help flags-as-proto | base64 --decode | protoc --decode bazel_flags.FlagCollection bazel_flags.proto

outputs:

[ other options... ]

flag_infos {
  name: "bazelrc"
  has_negative_flag: false
  documentation: "The location of the user .bazelrc file containing default values of Bazel options. /dev/null indicates that all further `--bazelrc`s will be ignored, which is useful to disable the search for a user rc file, e.g. in release builds.\nThis option can also be specified multiple times.\nE.g. with `--bazelrc=x.rc --bazelrc=y.rc --bazelrc=/dev/null --bazelrc=z.rc`,\n  1) x.rc and y.rc are read.\n  2) z.rc is ignored due to the prior /dev/null.\nIf unspecified, Bazel uses the first .bazelrc file it finds in the following two locations: the workspace directory, then the user\'s home directory.\nNote: command line options will always supersede any option in bazelrc."
  commands: "startup"
  allows_multiple: false
  effect_tags: "CHANGES_INPUTS"
  documentation_category: "BAZEL_CLIENT_OPTIONS"
  requires_value: true
}

[ other options... ]

The allows_multiple: false directly contradicts the documentation two lines above it, claiming that "This option can also be specified multiple times."
