Semver is translated in an invalid #tag

[Pictor13]

I tried to run bower-away on a bower package and got some @namepaced dependencies that cannot resolve the correct #tag, in the peerDependencies of package.json (when running npm install).

{
  "dependencies": {
    "jquery": ">=1.7.0",
    "microplugin": "0.0.x",
    "sifter": "0.5.x"
  },
  "devDependencies": {
    "bootstrap2": "bootstrap#2",
    "bootstrap3": "bootstrap#3.2"
  }
}

becomes

"dependencies": {
    "@bower_components/bootstrap2": "twbs/bootstrap#2",
    "@bower_components/bootstrap3": "twbs/bootstrap#3.2",
    "@bower_components/jquery": "jquery/jquery-dist#>=1.8.0 <2.1.0",
    "@bower_components/microplugin": "brianreavis/microplugin.js#0.0.x",
    "@bower_components/sifter": "brianreavis/sifter.js#0.5.x",
  },

and generates a

npm ERR! git rev-list -n1 0.0.x: fatal: ambiguous argument '0.0.x': unknown revision or path not in the working tree.
npm ERR! git rev-list -n1 %3E=1.8.0%20%3C2.1.0: fatal: ambiguous argument '%3E=1.8.0%20%3C2.1.0': unknown revision or path not in the working tree.

Example:
In the case of "@bower_components/sifter":"brianreavis/sifter.js#0.5.1" the correct tag to resolve would be pointed by "brianreavis/sifter.js#v0.5.1".

Is it a naming problem of the libraries, over the bower registry/manifest, or is bower-away missing from checking the existence of that #tag on the repositories that are being required?

While digging I've found this #322 and I am wondering if it makes sense to use the ver.si.on in order to generate a #tag (is it the case?).

I dunno much of node.js so am not sure where the _target, in the script, is coming from.
