Here is a version, that should do, what the OP wanted:
fu! <sid>JumpInFile(forward)
redir => a |exe ":sil jumps"|redir end
let b = split(a, '\n')[1:]
let idx = match(b, '^>.*')
if idx == -1
return "\<esc>"
endif
let idx = (a:forward ? idx-1 : idx+1)
let i = 0
if get(b, idx, -1) != -1
let entry = matchlist(get(b, idx),
\ '^\s*\(\d\+\)\s\+\(\d\+\)\s\+\(\d\+\)'.
\ '\s\+\(.*\)')
if empty(entry)
return "\<esc>"
endif
if !empty(entry[4])
let line = matchstr(getline(entry[2]+0), '^\s*\zs.\{'.
\ strwidth(entry[4]).'}')
else
let line = getline(entry[2]+0)
endif
if line ==# entry[4]
if a:forward && entry[1] > 0
return (entry[1]) . "\<C-O>"
elseif !a:forward && entry[1] > 0
return (entry[1]-1) . "\<C-I>"
endif
else
return "\<esc>"
endif
endif
return "\<esc>"
endfu
nnoremap <expr> g<C-O> <sid>JumpInFile(1)
nnoremap <expr> g<C-I> <sid>JumpInFile(0)
