sscanf/strtoul: parse integers robustly
* builtin-grep.c (strtoul_ui): Move function definition from here, to... * git-compat-util.h (strtoul_ui): ...here, with an added "base" parameter. * builtin-grep.c (cmd_grep): Update use of strtoul_ui to include base, "10". * builtin-update-index.c (read_index_info): Diagnose an invalid mode integer that is out of range or merely larger than INT_MAX. (cmd_update_index): Use strtoul_ui, not sscanf. * convert-objects.c (write_subdirectory): Likewise. Signed-off-by: Jim Meyering <jim@meyering.net> Signed-off-by: Junio C Hamano <junkio@cox.net>
