[Bug 1248044] Re: xzless report an error

[Jean-Max Reymond]

The cause is the verbose output of less -V.
So, I fixed with

diff /usr/bin/xzless /tmp/xzless
49c49
< if test "$(less -V | { read ver && echo ${ver#less }; })" -ge 429; then
---
> if test "$(less -V | awk '{if (NR ==1) print $2}')" -ge 429; then
