phabricator: avoid a stacktrace when command arguments are missing
Previously, the TypeError wasn't properly converted to a SignatureError when
improper arguments were supplied to the inner function, because the stack depth
is 2 inside the vcrcommand decorator. The `__name__` and `__doc__` attributes
need to be reassigned to the new wrapper so that the help summary is available.

#require test-repo execbit
$ . "$TESTDIR/helpers-testrepo.sh"
$ cd "`dirname "$TESTDIR"`"
look for python scripts without the execute bit
$ testrepohg files 'set:**.py and not exec() and grep(r"^#!.*?python")'

look for python scripts with execute bit but not shebang
$ testrepohg files 'set:**.py and exec() and not grep(r"^#!.*?python")'

look for shell scripts with execute bit but not shebang
$ testrepohg files 'set:**.sh and exec() and not grep(r"^#!.*(ba)?sh")'

look for non scripts with no shebang
