Subject: bug#29020: [PATCH] gdb-mi doesn't display prompt when attaching
Date: Fri, 27 Oct 2017 11:28:00 -0400

This patch is pretty straightforward.  When we write a console message
to the GUD buffer, we now reset a variable that is used to determine
whether to print the gdb prompt on the next '^done' or '*stopped'
message.
