[syslinux] multiple ".." support

I haven't tested other directives regarding this issue; only CONFIG+APPEND, using several versions from 4.03 up to 4.06-pre6, and using many different paths. I also tried config.c32, but with the same results. Although the specific result changed in 4.04 (because of the support for one "../" and for "../../otherdirectory/") it is still not the intended base directory (when using SYSLINUX), as my "EXAMPLE C" shows.

If needed, I could upload one floppy image with the examples I presented in my previous message.

If there is some other directive or any method for me to test whether this is specific to CONFIG or otherwise a general SYSLINUX issue, please let me know.

I'll be waiting for some new testing version to repeat my tests with different paths.

TIA.
