Public bug reported:
If ~/.lessfilter exists and is used by lesspipe/lessfile, then lessfile
will make the filename of the temporary file visible in less. The
attached patch fixes this. (The filename is echoed to less after the
subshell exits; trying to do it inside the subshell means it ends up
looking to less like part of the file being viewed.)
To test this, you can place the following file at ~/.lessfilter:
#!/bin/sh
echo foo
exit 0
Then opening any file in less (assuming you have lessfile set up) should
show "foo". The bug is that, currently, it also shows a filename from
somewhere in /tmp.
