text file processing

Hello!
There is a text file, that contains hierarchy of menues, like:

Aaaaa->Bbbbb
Aaaaa->Cccc
Aaaaa-> {spaces} Ddddd (it means that the full path is Aaaaa->Cccc->Ddddd )
Aaaaa-> {more spaces} Eeeee (it means that the full path is Aaaaa->Cccc->Ddddd->Eeeee )
Fffffff->Ggggg
Fffffff-> {spaces} Hhhhh (it means that the full path is Fffffff->Ggggg->Hhhhh)
Fffffff-> {more spaces} Iiiiiiii (it means that the full path is Fffffff->Ggggg->Hhhhh->Iiiiiiii )

I used

$ awk '{if (index ($0, "->")>0){print base $0} else {base = $0}}' j8.txt > j9.txt

to get Aaaaa-> and Ffffff-> in front of lines, but it is only one level.
How I can get full paths in front of every element? I tried to use egrep with regex '.+-+>+[^ ]+' to find Aaaaa->Bbbbb, Aaaaa->Cccc and Fffffff->Ggggg, but I also need to insert them before... And there are 4 levels.... Maybe piping...

Thank you! (I hope everyone can understand what I mean... English is not my native language)

systemd-path

SYSTEMD-PATH(1) 						   systemd-path 						   SYSTEMD-PATH(1)

NAME

       systemd-path - List and query system and user paths

SYNOPSIS

       systemd-path [OPTIONS...] [NAME...]

DESCRIPTION

       systemd-path may be used to query system and user paths. The tool makes many of the paths described in file-hierarchy(7) available for
       querying.

       When invoked without arguments, a list of known paths and their current values is shown. When at least one argument is passed, the path
       with this name is queried and its value shown. The variables whose name begins with "search-" do not refer to individual paths, but instead
       to a list of colon-separated search paths, in their order of precedence.

OPTIONS

       The following options are understood:

       --suffix=
	   The printed paths are suffixed by the specified string.

       -h, --help
	   Print a short help text and exit.

       --version
	   Print a short version string and exit.

EXIT STATUS

       On success, 0 is returned, a non-zero failure code otherwise.
