#56434: Inconsistent flag names --nosync and --no-mirror

 Priority:  Normal      |  Milestone:  MacPorts 2.5.0
Component:  base        |    Version:  2.4.99

 `sudo port selfupdate` accepts a flag `--nosync`.

 `sudo port fetch` accepts a flag `--no-mirrors`.

 It is confusing that one of the flags uses a hyphen (`-`) between words
 and the other does not.

 Since `--no-mirrors` is new for MacPorts 2.5.0 which was not been released
 yet, we could easily change it to `--nomirrors` before release without
 introducing confusion for most users.

 Or, if we like the hyphenated version better, we could change the
 selfupdate flag to `--no-sync`, while keeping `--nosync` for backward
 compatibility. I don't see any other multiword options that aren't
 hyphenated, so this is probably the alternative I'd go with.
