Looks like an APR bug in win32/proc.c:apr_proc_create:

    cmdline = "";
    for (i = 1; args && args[i]; ++i) {
        if (has_space(args[i])) {
            cmdline = apr_pstrcat(pool, cmdline, " \"", args[i], "\"", NULL);
        else {
            cmdline = apr_pstrcat(pool, cmdline, " ", args[i], NULL);

Subversion passes an empty string, a single '\0' character, has_space
will return NULL, and so apr_pstrcat will just add a space without
