Subject: pager: always override LESS
X-Git-Tag: v198~10
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=a4c41bf3fa905c38e6e4d159c13eed890d53838b

pager: always override LESS

https://bugzilla.redhat.com/show_bug.cgi?id=868383

Primary reason to do this is to ensure "-e" works as intended, and is
not ignored because the user set his own LESS variable.
