builtin/commit-graph.c: don't accept common --[no-]progress

ttaylorr · gitster · commit d5fdf3073aba · 2021-09-20T11:01:23.000-07:00
In 84e4484 (commit-graph: use parse_options_concat(), 2021-08-23) we unified common options of commit-graph's subcommands into a single "common_opts" array. But 84e4484 introduced a behavior change which is to accept the "--[no-]progress" option before any sub-commands, e.g., git commit-graph --progress write ... Prior to that commit, the above would error out with "unknown option". There are two issues with this behavior change. First is that the top-level --[no-]progress is not always respected. This is because isatty(2) is performed in the sub-commands, which unconditionally overwrites any --[no-]progress that was given at the top-level. But the second issue is that the existing sub-commands of commit-graph only happen to both have a sensible interpretation of what `--progress` or `--no-progress` means. If we ever added a sub-command which didn't have a notion of progress, we would be forced to ignore the top-level `--[no-]progress` altogether. Since we haven't released a version of Git that supports --[no-]progress as a top-level option for `git commit-graph`, let's remove it.
