[elreq] Characters at line end and start (#127)

r12a has just created a new issue for https://github.com/w3c/elreq:

== Characters at line end and start ==
This appears to be fine, as the following characters will not wrap alone to the next line: ? ! ¡ ።) ] } / % – ” › » ፡ ፣ ፤ ፥ ፦.

See [the tests here](https://github.com/w3c/i18n-tests/wiki/Test-script-for-Line-breaking#default-line-breaking).
