License situation is problematic #29

The plugin claims to be under the "MIT" license: https://github.com/guns/vim-sexp/blob/master/plugin/sexp.vim#L12

However it's impossible for anyone looking to build upon (pieces of) your work to comply with this license. Assuming you meant this license:

Copyright (c) <year> <copyright holders>

Permission is hereby granted, free of charge, to any person obtaining a copy

The above copyright notice and this permission notice shall be included in all

OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE
SOFTWARE.

Note that it says "The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software." This plugin itself violates this requirement, and it's impossible to copy this license to derivative works because the notice wasn't in the original to begin with.

Thanks for pointing this out @orlp. I've added the license. Hope you find this plugin useful!
