improvement: add '-' for each <li> element found

[pippinmole]

Hi,

Thank you for introducing #84. I wonder if we could build more onto this, such as introducing - characters for every <li> that occurs in the description?

Currently, a description like this:

will output a description like so:

What you will get in return:
Fantastic market leading Pension scheme
Excellent employee health and wellbeing services including an Employee Assistance Programme
Exceptional starting annual leave entitlement, plus bank holidays
Additional paid closure over the Christmas period
Local and national discounts at a range of major retailers

what I'm suggesting is, we append the - character (which could be customizable to the library user), so there is at least some knowledge that it was a list element:

What you will get in return:
- Fantastic market leading Pension scheme
- Excellent employee health and wellbeing services including an Employee Assistance Programme
- Exceptional starting annual leave entitlement, plus bank holidays
- Additional paid closure over the Christmas period

Thanks
