flag values that start with a hyphen are interpreted as short options and cause option parse errors.

[adrian-thurston]

It's not possible to use long option arguments starting with -, when the long option is in the form --opt arg. The command line parsing library attempts to interpret the argument as a short option. For example:

+ ./bin/linux/influx query --host http://thurston05:8086/ --org monitor --token -3PpF_ISBadt4tS7e0BaKte1zDxryDwwb86cTQnUPmwau2UWe18rhCmMAHyJB-OZRZpfMp-3eYfEXQV_Au6I2A== 'from( bucket: "apps" ) |> range( start: 2021-09-14T19:03:20.021849485Z )'
Incorrect Usage: flag provided but not defined: -3PpF_ISBadt4tS7e0BaKte1zDxryDwwb86cTQnUPmwau2UWe18rhCmMAHyJB-OZRZpfMp-3eYfEXQV_Au6I2A

Removing the - from the token and adding it to the org causes a different error, likely the same root cause:

+ ./bin/linux/influx query --host http://thurston05:8086/ --org -monitor --token 3PpF_ISBadt4tS7e0BaKte1zDxryDwwb86cTQnUPmwau2UWe18rhCmMAHyJB-OZRZpfMp-3eYfEXQV_Au6I2A== 'from( bucket: "apps" ) |> range( start: 2021-09-14T19:03:20.021849485Z )'
Error: at most 1 query string can be specified as an argument, got 3

And finally, no leading - in any long option argument, option parsing succeeds:

+ ./bin/linux/influx query --host http://thurston05:8086/ --org monitor --token 3PpF_ISBadt4tS7e0BaKte1zDxryDwwb86cTQnUPmwau2UWe18rhCmMAHyJB-OZRZpfMp-3eYfEXQV_Au6I2A== 'from( bucket: "apps" ) |> range( start: 2021-09-14T19:03:20.021849485Z )'
Error: failed to execute query: 401 Unauthorized: unauthorized access

@danxmoran found this PR that attempted to fix it, but it was closed as stale due to edge cases.

As a workaround, the option can be specified as --opt=arg.
