" Tom Ryder (tejr)'s vimrc

"
" This is a 'literate vimrc', in the Donald Knuth tradition. It's long, and
" comments abound.
"
" This file should be saved as "vimrc" in the user runtime directory. (UNIX
" ~/.vim, Windows ~/vimfiles). It requires Vim 7.0 or newer with +eval, not
" running in &compatible mode. The vimrc stub (UNIX ~/.vimrc, Windows
" ~/_vimrc) that loads this file checks that these conditions are met.
"
" > And I was lifted up in heart, and thought
" > Of all my late-shown prowess in the lists,
" > How my strong lance had beaten down the knights,
" > So many and famous names; and never yet
" > Had heaven appeared so blue, nor earth so green,
" > For all my blood danced in me, and I knew
" > That I should light upon the Holy Grail.
" > --Tennyson

" Set an environment variable MYVIM for the user runtime directory, if such
" a variable does not already exist in the environment, and there's a value in
" 'runtimepath' from which to glean a useable path. We'll use the path
" nominated in the MYVIM variable as the root of our 'backupdir', 'directory',
" 'undodir', and 'viminfofile' caches.
"
" I think the absence of a variable like this is a glaring omission from Vim.
" We have $VIM, $VIMRUNTIME, and $MYVIMRC, so why is there not an environment
" variable for the first runtime directory? It's a mystery, and that's why so
" is mankind.

" Global indent settings go here. Filetype indent plugins will often refine
" these settings for individual buffers. For example, 'expandtab' is not
" appropriate for Makefiles, nor for the Go programming language. For
" another, two-space indents are more traditional for Vim script.
"
" In general, however, I prefer spaces to tabs as a default, and I like to use
" four of them, for a more distinct visual structure. Should you happen to
" disagree with this, I cordially invite you to fite me irl.

" back as v5.8.0 (2001), and 'undodir' appears to have supported it since its
" creation in v7.2.438. Even though the :help for 'backupdir' didn't say so,
" people assumed it would work the same way, when in fact Vim simply ignored
" it until v8.1.251.
"
" I don't want to add the slashes to the option value in older versions of Vim
" where they don't do anything, so I check the version before I add them.
