PATCH: Minor cleanup for Insight command-line

[Tom Tromey <tromey at redhat dot com>]

I recently submitted an Insight patch which changes how external
editors are handled.  It has already been approved.  The Insight patch
requires a minor gdb/main.c patch, which is appended.

I think this patch should be uncontroversial because it only removes
code, including a global variable.

We can't get rid of `--enable-external-editor', unfortunately, as
existing Source Navigator installs will still use it.

Ok to commit?  My Insight patch is waiting on this.  If I check that
patch in without this, gdb won't build.
