However zmore(1) is able to handle uncompressed files transparently while zless(1) is not. Add another case to the switch in lesspipe.sh to handle non-compressed files.

The current FreeBSD /usr/bin/zless: export LESSOPEN="||/usr/bin/lesspipe.sh %s" exec /usr/bin/less "$@" displays a blank page when attempting to read a file that is not compressed. GNU versions: if test "${LESSMETACHARS+set}" != set; then # Work around a bug in less 394 and earlier; # it mishandles the metacharacters '$%=~'. space=' ' tab=' ' newline=' ' LESSMETACHARS="$space$tab$newline'"';*?"()<>[|&^`#\$%=~' export LESSMETACHARS fi LESSOPEN="|-gzip -cdfq -- %s"; export LESSOPEN exec less "$@" work as expected.
