More than one references in a line

[JustBlackBird]

Comments starts with #: can contain more than one references per line. For example, if xgettext is used with standard input a reference comment can contains the following:

#: standard input:11 standard input:26
msgid "One"
msgstr ""

At the same time, PO.parse finds only one reference is such cases (standard input:11 standard input:26 for the example above).

I can confirm this. However, it's not quite clear, how this case should be handled. The documentation does not specify the format of references in a very specific way. Loading the example from above in lokalize (translation tool in kde-sdk) will result in 4 references, standard, input:11, standard, input:26. So this tool splits at spaces, which this library doesn't. IMHO both variants would be okay. So I'd leave this as is and document it with a new test case. However, I'd be equally fine with the "split at spaces" approach.

Opened PR #14 to discuss how this issue can be solved.

References in a comment have file_path:line format. We can try to get them with a regular expression.

something like /.*:[0-9]+/? Could be possible, sure. But as I said before, this is in no way specified, anywhere. At least, not that I'm aware of. So whichever way we implement, we will always break someones workflow.
