PS: the function looks like this now:
enum eol eol_for_path(const char *path, const char *src, size_t len)
{
struct conv_attrs ca;
struct text_stat stats;
convert_attrs(&ca, path);
if (output_eol(ca.crlf_action) != EOL_CRLF)
return EOL_LF;
if (!len || ca.crlf_action != CRLF_AUTO &&
ca.crlf_action != CRLF_GUESS)
return EOL_CRLF;
ca.crlf_action = input_crlf_action(ca.crlf_action, ca.eol_attr);
gather_stats(src, len, &stats);
if (ca.crlf_action == CRLF_GUESS && stats.cr > stats.crlf)
return core_eol;
else if (stats.crlf)
return EOL_CRLF;
else
return EOL_LF;
}
