Use previous count when 'x' command is repeated
About the 'x' command, the manual says:
If you use <RET> to repeat the 'x' command, the repeat count N is
used again; the other arguments default as for successive uses of
'x'.
However, PR gdb/22619 points out that this does not work.
This patch fixes the problem.
