ui: only use "user@host" as username in noninteractive mode We regularly see people on IRC ask how they can correct commits they accidentally made without having configured a username. This change will make Mercurial abort when a commit is made without a username. If Mercurial is run without a TTY (from a cronjob or similar), a username is constructed as usual. Schematically the changes are as follows: With ui.askusername=False: old new interactive user@host abort noninteractive user@host user@host With ui.askusername=True: old new interactive prompt prompt noninteractive user@host user@host
