[PATCH] allow shell-quoting in command defaults

[TK Soh]

Just found out that shell quoting doesn't work in command defaults:

    % hg debugconfig | grep export
    defaults.export=-o "PATCH %b_rev%R.diff"

    % hg export tip
    abort: unknown revision '%b_rev%R.diff"'!

Please review and command on this patch for a fix:
