Subject: xzless: Fix less(1) version detection when it contains a dot.
X-Git-Tag: v5.3.2alpha~10
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=96f5a28a46fc93ac4e296808ac0f8631d05498bc;p=thirdparty%2Fxz.git

xzless: Fix less(1) version detection when it contains a dot.

Sometimes the version number from "less -V" contains a dot,
sometimes not. xzless failed detect the version number when
it does contain a dot. This fixes it.

Thanks to nick87720z for reporting this. Apparently it had been
reported here <https://bugs.gentoo.org/489362> in 2013.
