A vertical bar | is not handled properly.

[shinnkondo]

html2haml does not treat | well when it appears as the last character of an element.

Problem

Let's say I have the following html.

<span>|</span>

It is converted to

%span |

in haml, which is rendered back to

<span></span>

in html. As you can see, the | is missing because it at the end of line is treated as a line separator.

Solution

One solution is to print the following as a haml:

%span 
  |

Using ruby works, too.

%span= "|"

But don't know if converting a plain text to ruby is a good thing to do.

When this happens?

I had this case when I was to print links in a loop, with | as separator(Just imagine a category sub-header like "Ruby | Haml" for an article ).

It might be the case that I can avoid the problem by the way I write html, but it would be nice if conversion works for any html.

So what I want?

I am guessing that https://github.com/haml/html2haml/blob/master/lib/html2haml/html.rb#L389 (where it checks if text can be in the same line as a parent element) would be a good place to check |;(Code and and after is what I added)

if !child.to_s.include?("\n") and !uninterp(child.to_s).end_with?(Haml::Parser::MULTILINE_CHAR_VALUE)

It passed the tests, and works fine with my case.

If that looks OK, I would write a pull request, or someone can integrate this.
If not, any suggestion, comment, advice, or fix would be appreciated.
