@evergreen-lee-campbell Thank you for your contribution.
I really can't reproduce #42 I created test files with Windows Notepad and Sublime Text with "windows line endings" options and no matter how many times i run this plugin i don't see additional linefeeds. Maybe i'm doing something wrong though so i guess we can do something like your PR. But i have some questions:

1. If the whole difference is that one \r in regex, could something like this:

/(\r?\n?)([ \t]*)(<!--\s*build:(\w+(?:-\w+)*)\s*-->)\n?([\s\S]*?)\n?(<!--\s*endbuild\s*-->)\n?/ig

or

/(\n?|\r\n?)([ \t]*)(<!--\s*build:(\w+(?:-\w+)*)\s*-->)\n?([\s\S]*?)\n?(<!--\s*endbuild\s*-->)\n?/ig

just work without any new config options? Could you test it please?
2. Could you change tabs to 4 spaces please? Formatting is pretty broken.

I like this option. And I already use @evergreen-lee-campbell 's repository in my package.json.

Notepad and sublime aren't attempting to do line endings normalization and basically ok with mixed LF and CRLF in one file. But if one using Visual Studio or there is a git autocrlf then there is an extra lines problem.

Regexp that solved problem for me:
var regex = /(\n|\r\n)?([ \t]*)(<!--\s*build:(\w+(?:-\w+)*)\s*-->)([\s\S]*?)(<!--\s*endbuild\s*-->)(\n|\r\n)?/ig;

I have tried, modified my local dependent version as what @evergreen-lee-campbell committed. it works fine! why @VFK doesn't merge it to master and release it?

I wrote a test case project as below:
https://github.com/chaijunkun/gulp_test

1. npm install
   2.npm test

template file is from src/index.html, and output file is dist/index.html.
in macOS, there will be two 0x0a (s) between the two tags:

endbuild
build:seg_2

but in Windows, the character 0x0a presents 3 times between the two tags.
