The last few commits resolved the KFAILs in gdb.base/args.exp. With
those out of the way we can clean up this test script a little.
In this commit I have:
- Stopped passing 'nowarnings' flag when building the source file.
I see no reason why this source should issue a warning,
- Moved setup of GDBFLAGS into args_test proc, callers that passed a
newline needed a small tweak, and also the matching code needs
updating for newline handling, but I think this is nicer, the
argument lists are now given just once,
- Updated comment on args_test,
- Updated other comments.
There should be no change in what is tested after this commit.
