Thanks.

Can we perhaps come up with a better name instead of `future-break'?  It 
doesn't really describe well enough what does this command do, IMHO.  For 
example, if it is possible to put a breakpoint at the time the user 
issues the command, GDB will do that without delays, so the word 
``future'' is inaccurate.

A related question is: maybe we should make all breakpoint commands 
behave like this by default?

The changes to the docs are approved, with a few minor comments (see 
below).

This aspect of save-breakpoints isn't mentioned in the gdb.texinfo 
patch.  Please add it; I think it's important to say that in the manual, 
since the radix has effect on features other than breakpoints.

This should be either ``future'' or @emph{future}, probably the former.

Is it really like hbreak or like break?  That is, does GDB set a 
hardware-assisted breakpoint?  If so, what happens on platforms which 
don't support hbreak?

Also, I'd suggest to add a sentence or two about the situations where 
this command could be useful.

If the command accepts an argument, the file name, the @item above should 
say this:

  @item save-breakpoints @var{filename}
