Place of the bug and fix

Hello,

I found out that gdb omits the first byte of memory in a special case. If the
reading of large amount of memory fails, the gdb tries to read just one byte at
first and then it reads smaller pieces of memory. In this case the first read
byte is omitted.

I have done some investigation of this behaviour and a probable bug in function
target_read_until_error in file target.c. I am attaching my fix.

Regards,
Tomas
