I have looked the busybox-source vi applet. There I have not found necessity in
special
prompt parsing. On mine, entering of my function there only will increase size
as it 
works with dynamic memory.

I have other offers for inclusion in libbb:
1) xgetcwd(). Source can get from util-linux*/lib/*.c
2) paster_patch_file_name(). For example, in libbb:recursive action current
situation
very bad: in recursive allocate many stack!

I also have other sh parser ;-) (not ash, only my original).
I think, it is necessary how to coordinate this work for reception of fine
result. 
The principal cause of a spelling of it consists that the current module in
cmdedit rather
trivial, parser in sh can not give a position in a command line for use in
cmdedit 
and as I necessary inclusions of this code in my additional applets: ftp and
mc.
