setup_work_tree: adjust relative $GIT_WORK_TREE after moving cwd When setup_work_tree() is called, it moves cwd to $GIT_WORK_TREE and makes internal copy of $GIT_WORK_TREE absolute. The environt variable, if set by user, remains unchanged. If the variable is relative, it is no longer correct because its base dir has changed. Instead of making $GIT_WORK_TREE absolute too, we just say "." and let subsequent git processes handle it.

run-command: introduce CHILD_PROCESS_INIT Most struct child_process variables are cleared using memset first after declaration. Provide a macro, CHILD_PROCESS_INIT, that can be used to initialize them statically instead. That's shorter, doesn't require a function call and is slightly more readable (especially given that we already have STRBUF_INIT, ARGV_ARRAY_INIT etc.).

test-subprocess: fix segfault without arguments Check if we even have a parameter before checking its value. Running this command without any arguments may not make a lot of sense, but reacting with a segmentation fault is unduly harsh. While we're at it, avoid casting argv by declaring it const right away.

run-command API users: use strvec_pushv(), not argv assignment Migrate those run-command API users that assign directly to the "argv" member to use a strvec_pushv() of "args" instead. In these cases it did not make sense to further refactor these callers, e.g. daemon.c could be made to construct the arguments closer to handle(), but that would require moving the construction from its cmd_main() and pass "argv" through two intermediate functions. It would be possible for a change like this to introduce a regression if we were doing: cp.argv = argv; argv[1] = "foo"; And changed the code, as is being done here, to: strvec_pushv(&cp.args, argv); argv[1] = "foo"; But as viewing this change with the "-W" flag reveals none of these functions modify variable that's being pushed afterwards in a way that would introduce such a logic error.
