Fix list truncate

[fivetentaylor]

Problem

The calculation of replaceText produces truncated lists sometimes. For example

Numbered lists

The existing approach for numbered lists with . in it

"1. Respond to the user to acnowledge their request. Be friendly, supportive, and concise.".split('. ').splice(1, 1).join('')
> 'Respond to the user to acnowledge their request'

While the new approach returns

"1. Respond to the user to acnowledge their request. Be friendly, supportive, and concise.".replace(/^\s*\d+\. /, "")
> 'Respond to the user to acnowledge their request. Be friendly, supportive, and concise.'

Bullet lists

The existing approach if a - is in the list

offsetText = "    - my bullet list with a - in it"
offsetText.split('- ').length > 1 ? offsetText.split('- ').splice(1, 1).join('') : offsetText
> 'my bullet list with a '

The updated approach

"    - my bullet list with a - in it".replace(/^\s*- /, "");
> 'my bullet list with a - in it'
