The old one did the precompose only in strbuf_getcwd(). We now precompose also the result of get_git_work_tree(). Two questions. * It is unclear to me why this makes a difference only when the precompuse configuration is set only in the local configuration. * As the leading part of the value placed in get_git_work_tree() comes from strbuf_getcwd() called by abspath.c:real_pathdup() that is called by repository.c:repo_set_worktree(), doesn't this potentially call precompse twice on the already precomposed early parth of the get_git_work_tree() result? I suspect that with the arrangement in your test, the argument given to set_git_work_tree() from setup.c:setup_discovered_git_dir() is always ".", and that dot is passed to repository.c:repo_set_worktree() which calls abspath.c:real_pathdup() to turn it into an absolute, where it has a call to strbuf_getcwd(). So with the provided test, I suspect there is no difference between the previous and this iteration in behaviour, as what is fed to precompose should be identical? What this iteration does differently is that inside real_pathdup(), if the string given to repo_set_worktree() is more than the trivial ".", it is appended to the result of strbuf_getcwd(), and the new code precomposes after such appending in real_pathdup() happens. It will convert the leading part twice [*] and more importantly the appended part is now converted, unlike the previous one? Side note: [*] hopefully precompose is idempotent? Relying on that property somewhat feels yucky, though. Puzzled... Will replace and queue, but I couldn't figure out what is going on with the help by the proposed log message, so... Thanks.
