wrong attribute matching if name contains "-"

[dorny]

Hi,

when attribute name contains "-", only second part is highlighted.
For example: in "data-bind" only "bind" si matched and highlighted

problem is here:
"patterns": [
{ "name": "attributes.tag.jade",
"begin": "([a-z]\w+)(=)",

should be:
"patterns": [
{ "name": "attributes.tag.jade",
"begin": "([a-z][A-Za-z0-9_-]+)(=)",

don't forget the "?" at the end :)

"begin": "([a-z][A-Za-z0-9_-]+)(=)?",
