[PATCH] kconfig: fix 'Save As' menu of xconfig

[Masahiro Yamada]

The 'Save As' menu of xconfig is not working; it always saves the
kernel configuration into the default file irrespective of the file
chosen in the dialog box.

The 'Save' menu always writes into the default file, but it would
make more sense to write into the file previously chosen by 'Load'
or 'Save As'.

The 'save as' may be used for out-of-tree kernel config saves, but the 
default 'save' should always save to the in-tree .config file, as before 
(and for the past 10+ years..)  If the kernel config was loaded from an 
out-of-tree location, it now saves back to that out-of-tree location, 
which is useless for the kernel compile..

I have always kept my hardware/system-specific kernel configs 
out-of-tree, and then applied them in-tree before compiling.

Now, I have to use 'save as' and type in the entire in-tree path 
(/usr/src/linux-5.1/.config) each time, in order to apply the specific 
config to the kernel, ready for compilation.

I think it is quite natural that
"save" overwrites the file being edited.

And, that is how the 'save' of menuconfig/nconfig works.

It is easy to do it without using xconfig.

cp /your/custom/config .config
