grdedit is broken from Julia

[joa-quim]

grdedit is not particularly useful from wrappers, except for options -L and -N.

G = GMT.peaks();
G2 = grdedit(G, flip=:v, Vd=1);    # Ignore spurious -J
        grdedit  -JX14c/9.5c -Ev
G == G2
true

and even if I save grid to disk an work on files, grid is not changed

gmtwrite("peaks.grd", G)
grdedit("peaks.grd", flip=:v, Vd=1, V=true)
   grdedit peaks.grd  -JX14c/9.5c -V -Ev
...

Hmm, file is still written to memory (but not flipped)

grdedit("peaks.grd", flip=:v, Vd=1, G="peaks.grd", V=true);
        grdedit peaks.grd  -Gpeaks.grd -JX14c/9.5c -V -Ev

But grid is not ud-flipped.

Maybe post on the gmt git page instead?
