Problem:    maparg() doesn't return the flags, such as <buffer>, <script>,
            <silent>.  These are needed to save and restore a mapping.
Solution:   Improve maparg(). (also by Christian Brabandt)

Return the rhs of mapping {name} in mode {mode}. When there
is no mapping for {name}, an empty String is returned.
maparg({name}[, {mode} [, {abbr} [, {dict}]]]) *maparg()*
When {dict} is omitted or zero: Return the rhs of mapping
{name} in mode {mode}. The returned String has special
characters translated like in the output of the ":map" command
listing.
When there is no mapping for {name}, an empty String is
returned.
The {name} can have special key names, like in the ":map"
command.
{mode} can be one of these strings:
"n" Normal
"v" Visual
"v" Visual (including Select)
"o" Operator-pending
"i" Insert
"c" Cmd-line
"s" Select
"x" Visual
"l" langmap |language-mapping|
"" Normal, Visual and Operator-pending
When {mode} is omitted, the modes for "" are used.
When {abbr} is there and it is non-zero use abbreviations
instead of mappings.
The {name} can have special key names, like in the ":map"
command. The returned String has special characters
translated like in the output of the ":map" command listing.
When {dict} is there and it is non-zero return a dictionary
containing all the information of the mapping with the
following items:
"lhs" The {lhs} of the mapping.
"rhs" The {rhs} of the mapping as typed.
"silent" 1 for a |:map-silent| mapping, else 0.
"noremap" 1 if the {rhs} of the mapping is remappable.
"expr" 1 for an expression mapping (|:map-<expr>|).
"buffer" 1 for a buffer local mapping (|:map-local|).
"mode" Modes for which the mapping is defined. In
addition to the modes mentioned above, these
characters will be used:
" " Normal, Visual and Operator-pending
"!" Insert and Commandline mode
(|mapmpde-ic|)
"sid" the Script local ID, used for <sid> mappings
(|<SID>|)
The mappings local to the current buffer are checked first,
then the global mappings.
This function can be used to map a key even when it's already
