Experiment: always set 'iskeyword' for erlang

[sanmiguel]

I've an experimental branch in my fork, here: https://github.com/sanmiguel/vim-erlang-tags/tree/set-iskeyword-for-erl-filetype which always does set isk+=: for erlang files, rather than needing the special bindings for erlang files.

Thoughts, comments, suggestions welcome as always

Initially I also always had : in isk, but it can be annoying when you have binaries and want to use keyword completion:

• With : not in isk:

  f(<<FirstVar:8, SecondVar:8>>) ->
    Fi<press CTRL-P> → FirstVar

• With : in isk:

  f(<<FirstVar:8, SecondVar:8>>) ->
    Fi<press CTRL-P> → FirstVar:8

I found two minor (and probably fixable) cases when this setting makes a difference in syntax highlighting:

• <<A:1>>: if : is in isk, the 1 is not highlighted.
• throw:Var: if : is in isk, Var is not highlighted.
