in thread Win32/Linux portability
I read it more than twice, before. It says "However, this special treatment can be avoided by specifying the pattern / / instead of the string " " , thereby allowing only a single space character to be a separator."
To me that means that for one or more ".", "." should work as well, or is there something special about a "." compared to a " "? |

or is there something special about a "." compared to a " "
No. The latter is special, the former is not.
When a single space is used as the first argument to split, it is treated specially, and is substituted for by a regex that is (approximately) equivalent to /\s+/.
This is a convenience token for a common case and (approximately) acts like a similar construct in another language.
There is no such special case for '.'.

No. Don't extrapolate from what the doc says. It says a special case is
"when the PATTERN is either omitted or a literal string composed of a single space character
(such as ' ' or "\x20")"
'.' is not a space character.
