Your mail software breaks long lines, which will be an annoyance for
whoever tries to apply these patches.  Please resend the patches while
taking care that long lines are sent intact, TIA.

I think these changes are confusing: the full name for
"../../../devo/gdb/testsuite/gdb.mi/basics.c" cannot possibly be
"/devo/gdb/testsuite/gdb.mi/basics.c" unless "../../.." resolves to
the root directory.  While the latter is a possibility, it's a very
rare occasion, so it is better to replace "../../.." with something
like "/foo/bar/", not with "/".  The way you did it, a user could
misunderstand what fullname= does: your examples look like it simply
removes "../../.." part.

Here, I don't understand the "/.../" part.  Did you mean for the 3
dots to stand for the omitted full path from the root?  If so, it's
less confusuing to use some invented file names, like /foo/bar/baz or
/dir/subdir/subsubdir.

Other than that, the doco patch is approved.  Thanks.
