New submission from Mingchii Suen <crazy95sun at gmail.com>:

in `platform.py`, `_sys_version_parser`
the last part of regex is `r'\[([^\]]+)\]?'`
which should be `r'(?:\[([^\]]+)\])?'

without this change, the question mark only make the last `\]` optional, not the whole part optional

this will cause unable to detect python implementation issue in some custom build python if the `[compiler]` part in `sys.version` is missing

will make a pull request soon
