"var-1" is divided incorrectly into "var" and "-1"

In Python mode (not sure whether this bug also exist in other language), var-1 should be divided into var (variable, which will be a text node after parsing), - (operator) , and 1 (number) . However, when there is no space between “-” and “1”, the string will be divided into var and -1(number).

The behavior is a bit inconsistent. The problem is, that the number definition for most languages begins with the following regex \b-?. The minus sign can also be a word boundary at the same time and \b is a zero-length match. This complicates things a bit:

• Case word -1: The zero-length \b matches between - and 1 because - is seen as a word boundary. So - will become an operator and 1 will be a number.
• Case word-1: The \b matches the end of word between d and -. This time - is part of the number.

We could make it more consistent and remove all -? from the number definitions of all languages. Then it would always be an operator.

Ok! Would probably simplify some regexps too 😃
