Escapes an argv-style argument array to be used with spawnShell, pipeShell or executeShell.

string url = "http://dlang.org/";
executeShell(escapeShellCommand("wget", url, "-O", "dlang-index.html"));

Concatenate multiple escapeShellCommand and escapeShellFileName results to use shell redirection or piping operators.

    escapeShellCommand("curl", "http://dlang.org/download.html") ~
    "|" ~
    escapeShellCommand("grep", "-o", `http://\S*\.zip`) ~
    ">" ~
    escapeShellFileName("D download links.txt"));
