I think I know the answer.  We show by default whatever the compiler
saw on its command line when it compiled the source file.  E.g., if
the command was

  gcc -c ... /foo/bar/baz.c

then GDB will show "/foo/bar/baz.c", but if the compilation command
was

  gcc -c ... baz.c

then GDB will show "baz.c".

Is that correct?  If so, calling this `full' is misleading, I think,
unless we really change GDB to always show a full absolute file name
there.  If we don't want to change, I suggest to call it `normal' or
maybe `default' (with explanation along the above lines).
