I don't know, but it drives me nuts.  This causes:

(gdb) break *0x10000000
Breakpoint 1 at 0x10000000
(gdb) watch *0x10000000
Watchpoint 2: *268435456
(gdb) info break
Num     Type           Disp Enb Address    What
1       breakpoint     keep y   0x10000000
2       watchpoint     keep y              *268435456

I'm sure there are some cases which are more ambiguous if you print
the string, but I'd risk some ambiguity to get rid of that :-)
