- GOPATH is no longer required
- fzf repository does not have to be in GOPATH
- Build Linux binary with Go 1.5.3

- Slightly more efficient processing of Options
- Do not return reference type arguments that are mutated inside the
  function
- Use util.Constrain function when appropriate

[man] Remove useless `.R` macros

If you do `man fzf > /dev/null`, you'll get the following output

`R' is a string (producing the registered sign), not a macro.
`R' is a string (producing the registered sign), not a macro.
`R' is a string (producing the registered sign), not a macro.
`R' is a string (producing the registered sign), not a macro.
`R' is a string (producing the registered sign), not a macro.
`R' is a string (producing the registered sign), not a macro.

Removing these `.R` macros with a newline seems to have no effect on the
page but gets rid of the error.

e.g. Opening another buffer when `set nohidden`

Note that $SHELL only points to the default shell instead of the current
shell. If you're on a non-default shell, you might want to override the
value like follows.

  SHELL=zsh fzf --bind 'enter:execute:echo $ZSH_VERSION; sleep 1'

e.g.

_fzf_complete_foo() {
  _fzf_complete "--multi --reverse --header-lines=3" "$@" < <(
    ls -al
  )
}

_fzf_complete_foo_post() {
  awk '{print $NF}'
}

[ -n "$BASH" ] && complete -F _fzf_complete_foo -o default -o bashdefault foo
