line break after square bracket

When a word beginning with a letter or letters in square brackets occurs at the end of a line, Scrivener 2.0.2 takes the liberty of allowing the remainder of the word to break to the next line. I can’t reproduce this behavior in TextEdit, so it’s potentially an incorrect, Scrivener-specific behavior.

Line break behaviour is all governed by the OS X text system and not by Scrivener itself, so this isn’t a bug (not with Scrivener anyway!).
All the best,
