Not quite.  Working directory is where the config file lives; there is a
set of search paths for both, but in the case of SYSLINUX the install
path gets automatically added to the top.

ISOLINUX supports ".." nowadays.

The thing is that the name to use if you want a common configuration
filename is syslinux.cfg; I do NOT want to support isolinux.cfg for
non-ISOLINUX simply because it is now defined explicitly as "the
filename to use if you only want ISOLINUX to read it" (there are people
who want the same file respository to work for ISOs and filesystem-based
USB sticks, but want slightly different behavior, mostly related to
chainloading.

So the patch is NAK, but most of the changes above have already happened.
