minor: remove trailing whitespace
Use actual value for SINGLE_QUOTES/DOUBLE_QUOTES
Add snippets `'`, `"` and `doc`

`'` and `"` use a new function `triple_quotes_handle_trailing` which
handles trailing/existing quotes.

This handles expanding `"_"`, where the second quote gets automatically
inserted by e.g. delimitMate.
Remove ; after "f"

Anonymouse functions may not need ; at most times.
