[Bug-apl] Misleading indentation

[Kacper Gutowski]

Attempting to compile r941 with g++ 6.3.0 fails due to it not liking
your coding style and -Werror:

Command.cc: In static member function ‘static bool 
Command::check_params(std::ostream&, const char*, int, const char*)’:
Command.cc:163:20: error: this ‘if’ clause does not guard... 
[-Werror=misleading-indentation]
          case '.': if (a[1] == '.' && a[2] == '.')
                    ^~
Command.cc:164:56: note: ...this statement, but the latter is misleadingly 
indented as if it is guarded by the ‘if’
                       many = true;                     continue;  // ...
                                                        ^~~~~~~~
