Subject: RFC: add more information to --list=build-info output?

The recent change of FMT_MAIN_VERSION from 9 to 10 in bleeding-jumbo
inspired me to look at what other information might be useful to see in
--list=build-info.

I came up with these:

Format interface version: FMT_MAIN_VERSION
Charset file version: CHARSET_V
Max. Markov mode level: MAX_MKV_LVL
Max. Markov mode password length: MAX_MKV_LEN

So, for 1.7.9-jumbo-6-fixes with the attached patch applied, the new
--list=build-info output looks like this:

Version: 1.7.9-jumbo-7RC
Build: linux-x86-sse2i
Arch: 32-bit LE
$JOHN is ./
Format interface version: 9
Rec file version: REC3
Charset file version: CHR2
CHARSET_MIN: 32 (0x20)
CHARSET_MAX: 126 (0x7e)
CHARSET_LENGTH: 8
Max. Markov mode level: 400
Max. Markov mode password length: 30
Compiler version: 4.6.3 20120306 (Red Hat 4.6.3-2)
gcc version: 4.6.3

What do you think?
Should I avoid adding information that is less likely to change (e.g.,
the Markov mode limits)?
Should I put Markov mode limits into one line, to save space for future
additions?
Is the charset file version useful at all? I just checked the contest
edition, and the version is still CHR2.

Is there other information which should have been added?

Frank
