downloaddwm-0e98090d653457488d74103dc44a1e2aba071895.tar.gz
removed fgets usage, increment offset until a line is read, dwm will drop all lines read in one call, except the first!!! one (previously it preferred the last) - but the current approach is simplier and works better for general purpose in conjunction with the offset handling
