Suggested patch
Hi All,
gdb.base/commands.exp:watchpoint_command_test() should be updated with another
expected line. In "continue with watch" test there should be lines 53|78
instead of 53|77. This is reproducible on x86_64 host, but only if hardware
watchpoints are disabled, otherwise test will stop at line 53, not 77-78:
$ gcc -DFAKEARGV -g gdb/testsuite/gdb.base/run.c -o
gdb/testsuite/gdb.base/commands
$ gdb/gdb gdb/testsuite/gdb.base/commands

Watchpoint 2 deleted because the program has left the block in
which its expression is valid.

commands.exp expects line 77, but it is line 78. Attached patch fixes it.
