I did not know about --version, thanks!
Might be nice to have the information reusable as well
(--config comes to mind). See below.

./config.status --recheck && ./config.status
should do what you intend.
Below is a patch which implements reusable configure information with
./config.status --config
I'm not sure whether I want $ac_cs_configure there as well -- is it
possible for it to contain more than one word?

* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): New option
`--config' for config.status, to output parseable configuration
command.
* doc/autoconf.texi (config.status Invocation): Document it.
