Jeff King	e6821d09e4	t: fix some trivial cases of ignored exit codes in loops These are all cases where we do a setup step of the form: for i in $foo; do set_up $i \|\| break done && more_setup would not notice a failure in set_up (because break always returns a 0 exit code). These are just setup steps that we do not expect to fail, but it does not hurt to be defensive. Most can be fixed by converting the "break" to a "return 1" (since we eval our tests inside a function for just this purpose). A few of the loops are inside subshells, so we can use just "exit 1" to break out of the subshell. And a few can actually be made shorter by just unrolling the loop.

Junio C Hamano	3af1cae469	show-branch: fix segfault when showbranch.default exists When running "git show-branch" without any parameter in a repository that has showbranch.default defined, we used to rely on the fact that our handcrafted option parsing loop never looked at av[0]. The array of default strings had the first real command line argument in default_arg[0], but the option parser wanted to look at the array starting at av[1], so we assigned the address of -1th element to av to force the loop start working from default_arg[0]. This no longer worked since `5734365` (show-branch: migrate to parse-options API, 2009-05-21), as parse_options_start() saved the incoming &av[0] in its ctx->out and later in parse_options_end() it did memmove to ctx->out (with ctx->cpidx == 0), overwriting the memory before default_arg[] array. I am not sure if this is a bug in parse_options(), or a bug in the caller, and tonight I do not have enough concentration to figure out which. In any case, this patch works the issue around.

Johannes Schindelin	11ee57bc4c	sort_in_topological_order(): avoid setting a commit flag We used to set the TOPOSORT flag of commits during the topological sorting, but we can just as well use the member "indegree" for it: indegree is now incremented by 1 in the cases where the commit used to have the TOPOSORT flag. This is the same behavior as before, since indegree could not be non-zero when TOPOSORT was unset. Incidentally, this fixes the bug in show-branch where the 8th column was not shown: show-branch sorts the commits in topological order, assuming that all the commit flags are available for show-branch's private matters. But this was not true: TOPOSORT was identical to the flag corresponding to the 8th ref. So the flags for the 8th column were unset by the topological sorting.
