FirstCommand (JGit - Parent 6.3.0.202209071007-r API)

java.lang.Object
- org.eclipse.jgit.internal.transport.parser.FirstCommand

```
public final class FirstCommand
extends Object
```
In a push, the client sends a list of commands. The first command is special, as it can include a list of capabilities at its end.
For example: "oid oid name\0cap1 cap cap3"
Not to be confused with FirstWant, nor with the first line of the reference advertisement parsed by BasePackConnection.readAdvertisedRefs.
This class parses the inputted command line and holds the results: the actual command line and the capabilities.
