Created by: LitoMore

Description

We should overwrite user's configuration of less.

How Has This Been Tested?

Actual behavior

The two commands below outputs a incorrect string.

LESS=FRX FORCE_HYPERLINKS=1 glab mr list

LESS=-R FORCE=HYPERLINKS=1 glab mr list

Expected behavior

GLab should overwrite user's configurations of less. We should always use LESS=FrX to run the less
