List index out of range error when checking types

[tysonzero]

Whenever hdevtools emits a warning message, which isn't all that infrequent, something like an unused import or a defined and not used variable will cause it to emit warnings. :HdevtoolsType will give a bunch of errors that make it a huge pain to use.

The code causing the issue is here:

let l:types = []
for l:line in split(l:output, '\n')
  let l:m = matchlist(l:line, '\(\d\+\) \(\d\+\) \(\d\+\) \(\d\+\) "\([^"]\+\)"')
  call add(l:types, [l:m[1 : 4], l:m[5]])
endfor

Since the regex does not correctly parse the warning message. Index 5 is out of range. Causing the following error messages to appear:

Error detected while processing function hdevtools#type:
line   30:
E684: list index out of range: 5
E116: Invalid arguments for function add
... (above two lines repeated often several times, taking up often a good third of the screen)

I personally think the onus is on vim-hdevtools to silently ignore those warnings. Since I will see them on save from hdevtools itself anyway, so I don't need them annoying me whenever I want to check types of things.
