A plugin that provides a text object for groups of empty lines.
UPDATE 2017-01-14: The behavior of this plugin has changed a bit.
Previously, a<Space> selected all of the blank lines between two non-blank
lines; both lines before and after the current line. However, I discovered
that the inner paragraph (ip) text object built in to Vim does this already.
Rather than duplicate existing functionality, I have changed a<Space> to
select only blank lines before the current one. So now you can choose lines
above with a<Space>, lines below with i<Space>, or all lines with ip.
a<Space> selects all of the blank lines from the current one to the previous
non-blank line (assuming the current one is blank); i<Space> selects all blank
lines starting with the current until the next non-blank line. For the purposes
of this plugin, "blank" means contains only whitespace. (A line with spaces
and/or tabs, but no other characters, is considered blank.)
This plugin depends on kana/vim-textobj-user.
