Wrap function is droping characters at wrap point

[cp-richard]

Wrap and WrapWith both lose the character at the wrap point

Test example :

import (
  "github.com/Masterminds/sprig"
  "html/template"
  "bytes"
)

func main() {
  // The template
  tpl := "Word Wrap Test\n{{.Name | wrap 11 }}\n"

  // The values to pass to the template
  vars := map[string]string{"Name": "123456789_123456789_123456789_123456789_1234567890"}

  // Compile the template
  t := template.Must(template.New("example").Funcs(sprig.FuncMap()).Parse(tpl))

  // Run the template, copying the output to the buffer.
  var b bytes.Buffer
  err := t.Execute(&b, vars)
  if err != nil {
      panic(err)
  }
  print(b.String())
}

Output showing issue - in the first split line 1 is lost and 2 starts the second line, and so on :

Word Wrap Test
123456789_
23456789_1
3456789_12
456789_123
567890

This appear to be an issue with goutils.

I have a PR to goutils that should hopefully fix this: Masterminds/goutils#26

FYI, @kti-richard

Since Masterminds/goutils#26 was merged, this bug should be taken care of once if a new release of goutils is cut and then consumed by sprig.

This should be resolved as of https://github.com/Masterminds/sprig/releases/tag/v2.17.0.

This is resolved so closing.
