scmutil: seen.union should be seen.update (
issue3476)
patch: keep patching after missing copy source (
issue3480)
When applying a patch renaming/copying 'a' to 'b' on a revision where
'a' does not exist, the patching process would abort immediately,
without processing the remaining hunks and without reporting it. This
patch makes the patching no longer abort and possible hunks applied on
the copied/renamed file be written in reject files.
keyword: wlock cmdutil.copy wrapper
Expanding/shrinking happens outside the wrapped copy function;
therefore write lock the repo.
keyword: support commit --amend (
issue3471)
Include a test as well.
