I'm sure you've investigated this, but you might also consider the -O
option to wget -- it probably isn't quite what you're looking for if you
are fetching multiple files (such as with --mirror), but when fetching
one file at a time it's quite a bit less drastic than recompiling the
kernel and putting extremely long file names on disk.
