Returns a list created by splitting string at each place that
matches the regexp argument.
Each element of the result list will consist of the
characters from string that lie between instances of the
text that matched regexp. The text that matched regexp
is not included in the result list.
Empty list elements will be generated if string contains
adjacent matches of regexp, or if it matches the text at
the start or end of string.
If regexp is an empty string then each character of
string becomes a separate element of the result list.
SplitChars defaults to the standard white-space characters (i.e. "@w").
See the nrematch man page for a description of regular expressions.
Note that nresplit always turns on the p switch so
all additional nre features are available by default.
This command is a super set of the standard split command.
The only difference is that a regular expression is used as the
splitter instead of a single set of characters.
