.vimrc: lower ctrlp window height

.vimrc: don't scan included files for insert mode completion

.vimrc: enable autoindent

.vimrc: t_Co should be set automatically nowadays If not, check your terminal settings and/or .bashrc or other sourced files. My current $TERM is set to xterm-256color by xfce4-terminal.

.vimrc: set termguicolors if $COLORTERM says it's possible

.vimrc: reset color for ColorColumn It used to be darker than background color, but lighter color isn't bad.

.vimrc: let color scheme set background

.vimrc: make comments slightly brighter (when running in cterm mode) Also explicitly use the original, not rehashed colors. My color tweaks probably only apply to one scheme anyway.

.vimrc: make vimdiff much less likely to fold lines It still could happen in very large files, in which case it could probably be actually desirable.

.vimrc: reverse colors for matching parentheses Otherwise it looks too much like the cursor itself.
