Subject: [PATCH 2/2] cmRST: match anonymous hyperlink syntax

Previously, the `cmake --help-command string` output would have an extra
trailing `_` after `string(JSON)` subcommand names because they are
anonymous hyperlinks in the source. Support matching a double underscore
so that it is removed in the `--help-*` output.
