+ [gropdf] Problem with '(' and '\' (\[rs])
+
+ Bpth these tokens have meaning for roff AND pdf strings. In
+ pdfs unbalanced parentheses have to be escaped (with '\') and
+ a single '\' has to be similarly escaped, '\\'. It is gropdf's
+ responsibility to ensure pdf strings are valid, no matter what
+ the input.
+
+ If '\(ul' is passed then the UTF-16 character becomes '_'.
+ If '\[rs](ul' is passed (i.e. '\(ul' is intended to become the
+ UTF-16 string) \[rs] becomes '\' leaving '\(ul', which
+ becomes '_', not what is intended. If the unbalanced '(' is
+ eascaped first, '\[rs]\(ul' which could become '\\_' when the
+ '\' is escaped, yielding '\_'. The code which escapes parenthesis
+ checks it is not already preceded by '\' since adding another
+ would give you '\\(' which is not what you want. The correct
+ output should be '\\\(ul' to achieve the correct pdf string.
+
+ This fixes the above issue (I hope).
