export: remove useless comparison between file object and string It was introduced at 31aa2e5b0750, where "template" argument could be a file object. After that, a306837f8c87 added "len(template)", so "template" must be a string now. Therefore, "fp != template" should always be True. It seems 31aa2e5b0750 was intended to work around a bug in TortoiseHg, and I'm sure I've fixed it completely in TortoiseHg source. https://selenic.com/pipermail/mercurial-devel/2011-February/028467.html

export: do not print '<fdopen>' as an output filename Because makefileobj() duplicates or wraps stdout, "fp != sys.stdout" didn't work correctly. Python doc states that special file objects are named in the form '<...>', and absolute filenames should never start with '<', we can ignore names start with '<'. We can't test fp.fileno() because fp may be a command-server channel. https://docs.python.org/2.7/library/stdtypes.html#file.name In the test output, "exporting patch:" line is printed after patch content. This is caused by fdopen() and will be fixed by the subsequent patch.

commandserver: implement name() to clarify channel is not a plain file Because unknown attributes are delegated to the underlying file object, commandserver channels said they were '<stdout>' or '<stdin>' even though they weren't. This patch makes them say '<X-channel>'.

histedit: delete to drop The default behaviour to forbid this makes a lot of sense for novice users because it's safeguarding them from dangerous behavior but making it configurable will be apprieciated by power users in at least one big organization. It allows an user to look an histedit rules from declarative perspective and make the rules reflect the state after histedit. If we can move lines t move commits why can't we drop lines to drop commits? Let's put this behind config knob and inform users about this feature the very moment they are trying to use it so they can choose desired behaviour.
