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.
