can we avoid using contractions in GDB messages? (was: "[commit] symfile.c (simple_overlay_update): Check for null return.")

[Joel Brobecker]

Just a suggestion. It's really a detail, and I won't push for us
to adopt this suggestion, but:

> +	if (minsym == NULL)
> +	  error (_("Error reading inferior's overlay table: couldn't "
> +		   "find `_ovly_table' array\n"
> +		   "in inferior.  Use `overlay manual' mode."));

I'm not very fond of contractions in error messages (or any message
printed by GDB). I know there is plenty of "prior art" of our use
of contractions in the output, but I just think it looks better to
spell words completely.  For the future, can we agree on avoiding
contractions?
