The creation of the Ada TAGS support in Emacs predates my involvement,
so unfortunately, I don't know the reasoning behind it, other than
what appears in the manual (wanting to differentiate between symbols
of the same name in different contents).  However, that wouldn't be
unique to Ada.

In the testing I've done, this patch works correctly and addresses the
original problem reported.  However, as I explored this a bit further
I discovered another issue that involves completion.  After typing
'Displ' and then `M-x completion-at-point`, the tag including the
suffix is completed (i.e., "Display_Message/p" is inserted into the
buffer, instead of just "Display_Message").
