gdb: handle calls to edit command passing only a linespec condition
While working on the previous commit to fix PR cli/28665, I noticed
that the 'edit' command would suffer from the same problem. That is,
something like:
(gdb) edit task 123
would cause GDB to break. For a full explanation of what's going on
here, see the commit message for the previous commit.
As with the previous commit, this issue can be prevented by detecting,
and throwing, a junk at the end of the line error earlier, before
calling decode_line_1.
So, that's what this commit does. I've also added some tests for this
issue.
