From: Teng Long <dyroneteng@xxxxxxxxx>
This commit introduces a new option "--[no-]stripspace" to git notes
append, git notes edit, and git notes add. This option allows users to
control whether the note message need to stripped out.
For the consideration of backward compatibility, let's look at the
behavior about "stripspace" in "git notes" command:
1. "Edit Message" case: using the default editor to edit the note
message.
In "edit" case, the edited message will always be stripped out, the
implementation which can be found in the "prepare_note_data()". In
addition, the "-c" option supports to reuse an existing blob as a
note message, then open the editor to make a further edition on it,
the edited message will be stripped.
This commit doesn't change the default behavior of "edit" case by
using an enum "notes_stripspace", only when "--no-stripspace" option
is specified, the note message will not be stripped out. If you do
not specify the option or you specify "--stripspace", clearly, the
note message will be stripped out.
2. "Assign Message" case: using the "-m"/"-F"/"-C" option to specify the
note message.
In "assign" case, when specify message by "-m" or "-F", the message
will be stripped out by default, but when specify message by "-C",
the message will be copied verbatim, in other word, the message will
not be stripped out. One more thing need to note is "the order of
the options matter", that is, if you specify "-C" before "-m" or
"-F", the reused message by "-C" will be stripped out together,
because everytime concat "-m" or "-F" message, the concated message
will be stripped together. Oppositely, if you specify "-m" or "-F"
before "-C", the reused message by "-C" will not be stripped out.
This commit doesn't change the default behavior of "assign" case by
extending the "stripspace" field in "struct note_msg", so we can
distinguish the different behavior of "-m"/"-F" and "-C" options
when we need to parse and concat the message.
