Summary: bu_vls_printf doesn't handle complex formats properly 

Initial Comment:
This was fixed for a simple case in bug no. 3163487, but this format string doesn't work:

        bu_vls_printf(gedp->ged_result_str, "%-*.*s| %-*.*s = %*.*s |\n",
                      indent, indent, " ",
                      maxwidth[0], maxwidth[0], fname.rows[i].fields[0].buf,
                      maxwidth[1], maxwidth[1], table->rows[i].fields[0].buf);

The result works for the first and second '%*.*s' fields but the last field width is ignored (with or without the '-').  I can work around it by building the string with sprintf and feeding that to bu_vls_printf.  I'll add a test case later today.

Message:
The bug actually exists with a simpler format string as may be seen in the
attached test case.  It seems that right justification in a
wider-than-strlen field doesn't work in second or later fields.
