Defines functions for each as autoload functions. I need to look into
weather it would be better to have this as a local function in a plugin.
The function for url encoding was taken from vim-unimpared:
https://github.com/tpope/vim-unimpaired
I don't need all the functionality it provides
The function for base64 encoding was taken from vim-base64:
https://github.com/christianrondeau/vim-base64
although I use it with mappings in the vim-unimpared style
[b and ]b base64 encode and decode respectively
[u url encodes characters that are normally encodede in a url
[U url encodes all characters
]u and ]U both urldecode all encodede characters
Writing mode is to be used when I am writing prose rather than code, for
example markdown files or emails.
Currently, it enables spellcheck and adds insert mode mappings that add
undo points when certain punctuation is inserted, such as full stops or
commas.
Currently this is used for markdown files, emails and git commits
