>Description:
lesspipe.sh (src/usr.bin/less/lesspipe.sh) breaks on filenames containing spaces. This is because it uses a naked $1 as the argument for decompress, gunzip, and bunzip2, where it should use "$1" instead.
>How-To-Repeat:
use lesspipe.sh or less(1) with the LESSOPEN environment variable set to use lesspipe.sh on a compressed file with spaces in its name
>Fix:
attached patch
