Error when linking to git://, ftp:// etc. URIs

[akoeplinger]

The following HTML produces validation errors:

<a href="git://github.com/mono/mono">Git</a>
<a href="ftp://ftp.example.com">FTP</a>
<a href="irc://irc.gimp.org/mono">IRC</a>
<a href="svn://svn.example.com">SVN</a>

../test.html: internally linking to git://github.com/mono/mono, which does not exist
../test.html: internally linking to ftp://ftp.example.com, which does not exist
../test.html: internally linking to irc://irc.gimp.org/mono, which does not exist
../test.html: internally linking to svn://svn.example.com, which does not exist

I tried passing in --href_ignore git, that changed nothing. I know that the proofer can't really validate the links, but shouldn't it just ignore them then, like it does with mailto: ?

It should; thanks for the report. I'll probably have to add a skip for any protocol that's not HTTP(S), since you can put pretty much anything there (eg. github-mac://openRepo).
