Subject: wt-status.c: split rebase detection out of wt_status_get_state()
X-Git-Tag: v2.9.0-rc0~12^2~6
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=bcd522a1495146113f8e08e84a6717c04508e197;p=thirdparty%2Fgit.git

wt-status.c: split rebase detection out of wt_status_get_state()

worktree.c:find_shared_symref() later needs to know if a branch is being
rebased, and only rebase, no cherry-pick, do detached branch... Split
this code so it can be used independently from other in-progress tests.
