Automatically reformat com32/lib/syslinux/load_linux.c using Nindent.

Do this for all files except HDT, gPXE and externally maintained
libraries (zlib, tinyjpeg, libpng).

Linux itself is fine with sp = 0 for a 64K segment, but perhaps other

Do not relocate the real-mode code above address 0x90000... that would
not be prudent.
