it is no longer possible to save a series of figures with anonymous (implicit) handles
Reported by Samuel GOUGEON (@sgougeon)
The new save() syntax now prevents handy usages such that
save("figures.scg",scf(0),scf(1),scf(2))
It forces to priorly give a named handle to each figure to be saved.
These additional steps make the language less handy than it was.
Since xsave() does not accept a vector of figure numbers, there is
no other way to proceed.
help xsave / Description tells:
For graphics xsave(file_name,win_num) use preferabily save(file_name,scf(win_num)).
This piece of advices is no longer right.
If you really want to remove xsave (ok, but..), then allowing
to pass directly implicit handles to save() would be useful.
Otherwise, xsave() could be upgraded in order to accept a vector
of figure numbers (or/and of implicit or explicit figure handles).
