amend: save commit message into ".hg/last-message.txt" Before this patch, commit message (may be manually edited) for "commit --amend" is never saved into ".hg/last-message.txt", because it uses "localrepository.commitctx()" instead of "localrepository.commit()": saving into ".hg/last-message.txt" is executed only in the latter. This patch saves commit message for "commit --amend" into ".hg/last-message.txt" just after user editing. This is the simplest implementation to fix on stable. Editing and saving commit message for memctx should be centralized into the framework like "localrepository.commit()" with "editor" argument or so in the future.
