Converting Jira lists with CRLF line-breaks adds erroneous whitespace to subsequent text

[arctus-io]

When using jira2markdown's convert() function on Jira lists with Carriage Return (CR) Line Feed (LF) (CRLF) style line-breaks the resulting markdown text adds erroneous whitespace to subsequent text after the last list item.

See below for a visual example of the conversion issue.

from jira2markdown import convert
jira_text = 'Line Before List: Sample text words words words:\r\n * Bulleted Item 1: Sample text words words words\r\n * Bulleted Item 2: Sample text words words words\r\n\r\nLine After List: Sample text words words words\r\nLine After List: Sample text words words words'

print(jira_text)

Input (jira_text printed):

Line Before List: Sample text words words words:
 * Bulleted Item 1: Sample text words words words
 * Bulleted Item 2: Sample text words words words

Line After List: Sample text words words words
Line After List: Sample text words words words

Input (jira_text with line-breaks visualized):

Line Before List: Sample text words words words:\r\n
 * Bulleted Item 1: Sample text words words words\r\n
 * Bulleted Item 2: Sample text words words words\r\n
\r\n
Line After List: Sample text words words words\r\n
Line After List: Sample text words words words

md_text = convert(jira_text)

Expected Output (md_text printed):

Line Before List: Sample text words words words:
- Bulleted Item 1: Sample text words words words
- Bulleted Item 2: Sample text words words words

Line After List: Sample text words words words
Line After List: Sample text words words words

Expected Output (md_text with line-breaks visualized):

Line Before List: Sample text words words words:\r\n
- Bulleted Item 1: Sample text words words words\r\n
- Bulleted Item 2: Sample text words words words\r\n
\r\n
Line After List: Sample text words words words\r\n
Line After List: Sample text words words words\r\n

print(md_text)

Actual Output (md_text printed):

Line Before List: Sample text words words words:
- Bulleted Item 1: Sample text words words words
- Bulleted Item 2: Sample text words words words
  
  Line After List: Sample text words words words
  Line After List: Sample text words words words

Actual Output (md_text with line-breaks visualized):

Line Before List: Sample text words words words:\r\n
- Bulleted Item 1: Sample text words words words\n
- Bulleted Item 2: Sample text words words words\n
  \n
  Line After List: Sample text words words words\n
  Line After List: Sample text words words words

As shown the conversion ends up replacing:

• \r\n in the list with \n
• \r\n\r\n at the end of the list with \n \n
• \r\n after the list with \n

Copy-and-Pasteable Snippet to replicate the issue:

from jira2markdown import convert

# Input with CRLF line-breaks 
jira_text = 'Line Before List: Sample text words words words:\r\n * Bulleted Item 1: Sample text words words words\r\n * Bulleted Item 2: Sample text words words words\r\n\r\nLine After List: Sample text words words words\r\nLine After List: Sample text words words words'

# Print input with line-breaks rendered
print("\njira_text:\n" + jira_text)

# Print input with line-breaks represented, not rendered
print("\nrepr(jira_text):\n" + repr(jira_text))

md_text = convert(jira_text)

# Print output with line-breaks rendered
print("\nmd_text:\n" + md_text)

# Print output with line-breaks represented, not rendered

print("\nrepr(md_text):\n" + repr(md_text))
