Just to clarify, I'm not generally advocating for more comments. I think this
is one of those cases where a good high-level overview is necessary. Within st,
word-wrap and newline handling is a larger algorithm with code scattered across
various data structures, state machines and functions. The code alone
is too microscopic to communicate the larger intent.

Even with a perfect understanding of what the existing code does, it's not
clear in this case what the code is intended to do. For an outsider this
makes definitively fixing the bug much harder and possibly error-prone.
