From the JDK tool-docs for javac of JDK 1.4:

> An argument file can include javac options and source filenames in
> any combination. The arguments within a file can be space-separated
> or newline-separated.

that means, file names must be quoted if they contain spaces.  No idea
whether this is true for JDK 1.2 or 1.3 as well (1.1 doesn't support
@argfile).
