Hints for Preparing Documents Most documents go through several versions (always more than you expected) before they are finally finished. Accordingly, you should do whatever possible to make the job of changing them easy. First, when you do the purely mechanical operations of typing, type so subsequent editing will be easy. Start each sentence on a new line. Make lines short, and break lines at natural places, such as after commas and semicolons, rather than randomly. Since most people change documents by rewriting phrases and adding, deleting and rearranging sentences, these precautions simplify any editing you have to do later. — Brian W. Kernighan, 1974

For easier editing and reuse of sentences, or even portions of lines of text, one can (and should) write sentences or sentence fragments on their own lines in digital contexts.
This way future edits or the ability to more easily cut and paste will far easier in addition to keeping your version control files simpler and easier to read and visually track your changes. (That is in many version control systems, instead of a change appearing to affect an entire paragraph, it will only show on the single line that was changed thereby making the change easier to see.)
This particular affordance may be a particularly useful one for note takers who expect to regularly reuse their notes in other contexts. Many forms of software (including Tex, LaTeX, and even markdown) will autowrap newlines so that a sentence broken up into clauses on multiple lines will properly wrap back into a proper looking single line when printed. Take care that in many Markdown versions adding two spaces at the end of a line will automatically create a newline in your text.
