Method handleArg0

src/CLI2.cpp:307–327

/////////////////////////////////////////////////////////////////////////// Arg0 is the first argument, which is the name and potentially a relative or absolute path to the invoked binary. The binary name is 'task', but if the binary is reported as 'cal' or 'calendar' then it was invoked via symbolic link, in which case capture the first argument as 'calendar'.

  // Capture arg0 separately, because it is the command that was run, and could
  // need special handling.
