The zsh _arguments completion function has the following syntax:
_arguments [ARGUMENTS_OPTIONS] [:] COMMAND_ARG...
Where the optional colon is used to disambiguate options consumed by the _arguments function itself.
If this colon is missing and the first COMMAND_ARG conflicts with one of the options supported by _arguments, then it is misinterpreted resulting in missing options or the "unknown match specification character" seen above.
