Possible inaccurate text on Chapter 6 Perl page

[Chris Staub]

On the Perl installation page in Chapter 6, the description for the -Dpager switch reads:

-Dpager="/usr/bin/less -isR"

This corrects an error in the way that perldoc invokes the less program.

According to ​the bug report that suggested the addition of that switch, the main reason for it was to add -R to the less invocation. However, "less -R" is now the default for Perl, if it finds a less binary. If less is not found, it will use more instead. Therefore, a better description for the -Dpager option would be that it ensures that less is used instead of more.
