Automate double pipe

[lukeed]

Unless cursor is within a string, the | should always appear in pairs so that it behaves just like a string.

EG: ' always triggers '' with the cursor in between quotes; same for doubles. With the exception of regex and strings, the pipe is never alone.

Perhaps, instead, a do snippet should be added?

do + (tab) ==> do ${1:| |}. 1st tab is ability to delete entire parameter. 2nd tab is enter the parameter. 3rd is next line, indented
