Problem scenario
You are using a web browser and some items in a list are indenting where you do not want them indented. How do you make them line up with the other items in the list without indentation?
Solution
Bitbucket's rendering of a text file does an auto-indent for natural numbers (with no sub-numbering scheme). If you have this in a file, you'll get an unintended indentation for #3:
1.a
1.b
2.a.
2.b.
2.c.
3.
4.a.
The number three item has no sub-part. The sub-numbers could have been Roman numerals. Bitbucket recognizes the sub-numbers and never indents those numbers. In this situation if #3 has only one part, give it a sub-number (e.g., 3.a.). Then there will be no accidental indentation.
