alias_command does not detect that the prefixes of the alias command and the
aliased command are not matching: it is comparing the alias prefix
with itself, instead of comparing it with the aliased command prefix.
This causes either the alias command to silently do nothing,
or to have GDB asserting:
(gdb) alias assigne imprime limite-elements = set print elements
../../binutils-gdb/gdb/cli/cli-cmds.c:1552: internal-error: void alias_command(const char*, int): Assertion `c_command != NULL && c_command != (struct cmd_list_element *) -1' failed.
A problem internal to GDB has been detected,
Fix the logic, and update gdb.base/alias.exp to test these cases.
