problem:
some layer packages lists have the open and closing parentheses on the same line
as the first and last listed package, but most seem to have them on a separate
lines.
solution:
put the open and close parentheses on separate lines, except for lists with only
a single package, they are written on the same line as the variable name and
parentheses.
fix the lists indentation
Had to create dummy init functions at some places since the owner of a package
is the last layer that defines the init function of a package. And a package
can be installed only if it has an owner.
Change the key bindings:
- Remove SPC m p
- Better support for double leader keys for preview (,, and M-m M-m)
- Graph indentation on SPC m =
Add support for smartparens when it is used for {} pair.
Update the doc.
