* src/devices/grolj4/lj4.cpp: Fix code style nits. Give the
anonymous `struct` type used for `paper_table` a name, so
that it can be passed to a template function C++98-conformantly.
- (lookup_paper_size): Use a (signed) `int` as the loop index,
- which happens to conform with the signedness of the function's
- return value as which it can be used. Use `array_length()` on
- `paper_table` instead of `sizeof` and division.
+ (lookup_paper_size): Use a `size_t` as the loop index. Use
+ `array_length()` on `paper_table` instead of `sizeof` and
+ division. Change return type to `ssize_t` so that we can
+ continue to return `-1` meaning "not found".
+ (main): Change type of local variable `n` to match altered
+ return type of `lookup_paper_size()`.
