I agree.  But that means MI commands that delegate to CLI will have to
process the arguments to modify the quoting, right?

It would be good to fix that now, yes.

However, I Think we need 2 different styles of quoting: one for file
names, the other for strings.  Otherwise, supporting the Windows
backslashes will be hard.  Also, there are messy cases such as this:

    (gdb) break "foo bar.c":'MyClass::MyMethod'

(I'm not even sure I quoted it correctly ;-).  Can we really use the
same quoting rules for both the file-name and class/method name in
such situations?

If you agree with me on the two quoting styles, you will also agree
that we need two different flavors of buildargv.

It's relevant, at least wrt backslashes in Windows file names: if you
type TAB with backslash being the last character, completion won't
work (it does TRT when there are backslashes further to the left of
the cursor, though).  Also, quoted file names, with or without
whitespace, aren't completed correctly, no matter if they use forward
or backslashes.
