Package: less
Version: 406-0
Severity: normal
I have always had "/bin/more" symlinked to "/usr/bin/less" and I
typically invoke the program as "more". This has never caused
problems in the past.
In less-406, invoking the program as "more" automatically sets
the LESS_IS_MORE mode, and there is no way to turn it off.
The LESS_IS_MORE mode is very broken for me. With TERM=xterm,
files less than one page in length can not be seen at all, because
they flash up on the screen and disappear too quickly.
This can be demonstrated for example with
env -i TERM=xterm LESS_IS_MORE=1 less /etc/issue
env -i TERM=xterm LESS_IS_MORE=0 less /etc/issue
env -i TERM=xterm LESS_IS_xxxx=0 less /etc/issue
The first two fail, the third works fine. Previously this didn't
affect much, but now that LESS_IS_MORE is automatically set, there's
no way to work around it.
The attached patch fixes two problems:
- "LESS_IS_MORE" is now only automatically set if the variable was not
specified in the environment.
- "LESS_IS_MORE" mode is only enabled if the variable is set
explicitly to the value "1", as specified in the manpage.
This makes the second example above work as expected.
The default behavior is therefore unchanged, but at least I can
make things work by setting "LESS_IS_MORE=0" in my environment.
