[Bug]: man plugin can break less if you already have LESS set in your env

[bmjsmith]

Expected behavior

bash-it plugin enable man should enable colouring for man pages.

Current behavior

bash-it plugin enable man causes less and every command that uses it e.g. git log, man, bat to break with the cryptic error No tags file.

Possible solution

I have export LESS=--quit-on-intr --RAW-CONTROL-CHARS in my .bashrc.

When the man plugin is enabled I get:
LESS=R-quit-on-intr --RAW-CONTROL-CHARS in my env.

I think this causes less to interpret this as -q -u -i -t etc. and the -t is enabling ctags support. There is no ctags file on my (default ubuntu) install. This causes every use of less to exit with the "No tags file" error. There's very little info around on what that means, this was hard to nail down.

This looks like a typo.

I think it should be export LESS="-R ${LESS:-}" or export LESS="--RAW-CONTROL-CHARS ${LESS:-}" or similar.

Context

Completely broke any command line tool using PAGER.

Steps to reproduce

bash-it plugin disable man
less somefile # works
export LESS="--quit-on-intr --RAW-CONTROL-CHARS"
bash-it plugin enable man
less somefile # probably doesn't work

Looks about right. Would you like to make a pull request?

Frankly I was not even sure the use of ${LESS:-} made any sense. please see PR #2289 and let me know if it's works for you.
