util: fix line length calc in _alpm_archive_fgets
74274b5dc347ba70 which added the real_line_size to the buffer struct didn't properly account for what happens when archive_fgets has to loop more than once to find the end of a line. In most cases, this isn't a problem, but could potentially cause a longer line such as PGP signature to be improperly read. This patch fixes the oversight and focuses on only calculating the line length when we hit the end of line marker. The effective length is then calculated via pointer arithmetic as: (start_of_last_read + read_length) - start_of_line Signed-off-by: Dave Reisner <dreisner@archlinux.org>
