histedit: use the editor gotten by "getcommiteditor()" for "message"

Before this patch, "hg histedit" for "message" uses "ui.edit()" for
commit message editing.

It shows original commit message, but not detail about the target
revision: status of each modified/added/removed files, for example.

This patch uses the editor gotten by "getcommiteditor()" instead of
"ui.edit()" for "message"

In "test-histedit-edit.t", this patch omits "fixbundle" invocation,
because it prevents from confirming the "HG: added f" line in commit
message by filtering " added " lines.

Omiting "fixbundle" invocation causes that the exit code of "hg
histedit" appears as one of command line: in this case, "hg histedit"
is aborted by (expected) exception raising.
