Great. Thanks. This part has now been committed.

Attached is a first attempt. I ended up writing a new testcase for it,
so we can collect all aliases of "delete" in that testcase. Hope it was
ok. This testcase causes 1 FAIL without the patch above.

I have a question: How can we test that GDB didn't return any output
from the command? "" seems to match anything...

I don't mind adding them, but I've never used these abbreviations.
I suggest we wait for people to complain before adding them as aliases.

        * gdb.base/del.c: New file.
        * gdb.base/del.exp: New testcase.
