xzless: Support compressed standard input
It can be somewhat confusing that
less < some_file.txt
works fine, whereas
xzless < some_file.txt.xz
does not. Since version 429, ‘less’ allows a filter specified in
the LESSOPEN environment variable to preprocess its input even if
it comes from standard input, if $LESSOPEN begins with ‘|-’. So
set $LESSOPEN to take advantage of this feature.
Check less’s version at runtime so xzless can continue to work
with older versions.
