Warning: read_line is deprecated since 1.38.
Reads an entire line from a file into a buffer.
Lines may be delimited with '\n', '\r', '\n\r', or '\r\n'. The delimiter is not written into the buffer. Text after a '#' character is treated as a comment and skipped. '\' can be used to escape a # character. '\' proceeding a line delimiter combines adjacent lines. A '\' proceeding any other character is ignored and written into the output buffer unmodified.
