[PATCH v3 6/7] builtin: patch-id: remove unused diff-tree prefix

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jerry Zhang <Jerry@xxxxxxxxxx>

>From a "git grep" of the repo, no command, including diff-tree itself,
produces diff output with "diff-tree " prefixed in the header.

Thus remove its handling in "patch-id".
