[Python-ideas] Show more info when `python -vV`

[INADA Naoki]

When reporting issue to some project and want to include
python version in the report, python -V shows very limited information.

$ ./python.exe -V
Python 3.6.0b2+

sys.version is more usable, but it requires one liner.

$ ./python.exe -c 'import sys; print(sys.version)'
3.6.0b2+ (3.6:86a1905ea28d+, Oct 13 2016, 17:58:37)
[GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.38)]

How about `python -vV` shows sys.version?


perl -V is very verbose and it's helpful to be included in bug report.
Some of them are useful and worth enough to include in `python -vV`.

$ perl -V
