Comma-separated flags (`--assignees`, `--labels`, `--add/remove-labels`,
`--add/remove-reviewers`, `--events`, login `--scopes`) silently accepted
stray commas and whitespace, producing values like `[""]` for empty input
or `["alice", "", "bob"]` for `--assignees=alice,,bob`. Those blanks
were then forwarded to the Gitea SDK, where they either triggered obscure
server errors or silently mutated state in unexpected ways.
Root cause: a mix of `strings.Split(s, ",")` and ad-hoc trim loops, none
of which rejected empty segments.
Introduce `modules/utils.SplitCSV` as the single parser for all CSV flag
values. It:
- returns `nil` for an empty or whitespace-only input (so callers can use
`len(x) == 0` to mean "not set", and `cmd.IsSet("...")` keeps
working),
- drops empty and whitespace-only segments anywhere in the input,
- otherwise trims surrounding whitespace from each remaining segment.
`cmd/flags.SplitCSV` is re-exported from `cmd/flags/csvflag.go` so
existing call sites read `flags.SplitCSV` without depending on a leaf
package that `modules/task` already imports them.
Convert the remaining raw `strings.Split(..., ",")` sites:
- `cmd/flags/issue_pr.go` (issue/pr --assignees, --labels and the
set/add/remove variants)
- `cmd/pulls/edit.go` (`--add-reviewers`, `--remove-reviewers`)
- `cmd/webhooks/create.go`, `cmd/webhooks/update.go` (`--events`)
- `modules/task/login_create.go` (login `--scopes`)
Drop the now-unused `"strings"` imports from the three cmd/* files.
Tests:
- `modules/utils/splitcsv_test.go` — table-driven coverage for empty,
whitespace-only, leading/trailing commas, internal empty segments,
surrounding whitespace, and re-imported identity with `flags.SplitCSV`.
- `cmd/flags/csvflag_test.go` — `GetValues` happy path, error path,
empty entry drop, and AvailableFields variants.
- `cmd/flags/issue_pr_test.go` — regression test for
`GetIssuePREditFlags` proving `SetAssignees/AddAssignees/...`
produce `nil` (not `[""]`) for empty input and trimmed slices for
mixed inputs.
