Bug#1011525: systemd: when running journalctl, $LESS is unconditionally set to FRSXMK

Package: systemd
Version: 251-2
Severity: minor

Note: on my machine, /usr/bin/pager points to the "less" alternative.

When I run journalctl, searching for strings in the "less" pager is
case-sensitive, while I have -i in $LESS.

I've eventually found that my LESS environment variable was replaced
by "FRSXMK", but this is not documented. I could see this by putting
a "pager" script in my $PATH, where I output the $LESS value.

Well, journalctl(1) mentions "FRSXMK", but nothing about the LESS
environment variable (these options could be passed as a "less"
argument), and what "default" means is ambiguous (when the user
defines $LESS, he changes the default).

If the user has his own LESS environment variable, it should be kept,
otherwise the behavior is surprising.
