Avoid a crash in source_cache::extract_lines
If the first requested line is larger than the number of lines in the
source buffer, source_cache::extract_lines could crash, because it
would try to pass string::npos" to string::substr.
This patch avoids the crash by checking for this case.
This version of the patch changes get_source_lines to return
std::string.
