Having worked with `TeX`, I am familiar that hyphens indicate
word locations favorable to line breaks. Therefore, I understand
that one wants a way to control whether or not breaks are allowed
at hyphens, even if words should not be broken normally.

Apparently, "break_on_hyphens" adds hyphen as a word delimiter.
With this notion, the behavior can be understood.
