#10719: restore messages generated on invalid compileall args
Before the introduction of filename arguments to compileall it gave semi useful
messages about not being able to 'list' names that weren't valid directories.
This fix restores that behavior. In addition to the test for this case, the
patch also adds a test for the default behavior of compileall when no arguments
are provided, and fixes a bug in one of the previously added tests.

| 138 The following explanation of HTTP serves to guide you through the | |
| 139 code as well as to expose any misunderstandings I may have about | |
| 140 HTTP (so you don't need to read the code to figure out I'm wrong | |
| 141 :-). | |
| 142 | |
| 143 HTTP (HyperText Transfer Protocol) is an extensible protocol on | |
| 144 top of a reliable stream transport (e.g. TCP/IP). The protocol | |
| 145 recognizes three parts to a request: | |
| 146 | |
| 147 1. One line identifying the request type and path | |
| 148 2. An optional set of RFC-822-style headers | |
| 149 3. An optional data part | |
| 150 | |
| 151 The headers and data are separated by a blank line. | |
| 152 | |
| 153 The first line of the request has the form | |
| 154 | |
| 155 <command> <path> <version> | |
| 156 | |
| 157 where <command> is a (case-sensitive) keyword such as GET or POST, | |

| 2887 | 168 |
| 169 Similarly, for output, lines ought to be separated by CRLF pairs | |

199 a request SPAM will be handled by a method do_SPAM(). If no |
| 2887 | 200 such method exists the server sends an error response to the |

| 204 | |
| 205 Note that the request name is case sensitive (i.e. SPAM and spam | |
| 206 are different requests). | |
| 207 | |
| 208 The various request details are stored in instance variables: | |
| 209 | |
| 210 - client_address is the client IP address in the form (host, | |
| 211 port); | |
| 212 | |

| 223 IT IS IMPORTANT TO ADHERE TO THE PROTOCOL FOR WRITING! | |

| 225 The first thing to be written must be the response line. Then | |

| 227 actual data (if any). The meaning of the header lines depends on | |
