Subject: Test the handling of some additional one-character escape sequences
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=4c6bf6b83bf8dc201ecd4746941140b7fbf36db1;p=openbsd

Test the handling of some additional one-character escape sequences
that take no argument and are ignored: \% \& \^ \a \d \t \u \{ \| \}
No change to parsing or formatting needed.
