I did test it.
1. `rm .config`
2. `make config`
3. Try answering N to all boolean question, and leave default values for all
non-boolean questions, except the "Choose which shell is aliases to 'sh' name",
in which I answer 1. (Otherwise it defaults to "3. none" since I answer N to
the ash choice) [screenshot1.png]
4. Then continuing answering N to everything... [screenshot2.png]
5. And it comes to "Restart config..." line! [screenshot3.png] [screenshot4.png]
And all ash options go prompted again!

Screenshots and the resulting config file are attached as proof.
The options that are skipped this way are all irrelevant to this ash
config change.
Either because they are choices
(INSTALL_APPLET_SYMLINKS, NO_DEBUG_LIB,
FEATURE_BUFFERS_USE_MALLOC and SH_IS_ASH, BASH_IS_NONE),
or they are skipped because of "select" clauses
(PLATFORM_LINUX and FEATURE_SEAMLESS_GZ).
All irrelevant to this.
