Commit Message

Fix binary number literal parsing.

Reported by Egor Skriptunoff.

(cherry-picked from commit 377a8488b)

A binary number with a fractional part is invalid. Parsing of such
binary numbers returns `STRSCAN_ERROR` for any numbers with a non-zero
fractional part because it gives a non-zero power of the exponent
(`ex2`) in `strscan_bin()`. But binary numbers with a zero fractional
part are considered valid numbers. To avoid such inconsistency the
check, that the given base doesn't equal 2, is added, when parsing the
decimal point part of the literal.

Sergey Kaplun:
* added the description and the test for the problem
