Details:

po_message_add_filepos and a subsequent PO file write don't implement
escaping. If you then read such unescaped paths with po_message_filepos, it
interprets the file path as paths to two files.

Steps to reproduce:

1. Modify a PO file with libgettextpo in a way to add a reference to file
"abc.txt/de f.txt".

2. In the output PO you get:

#: abc.txt/de f.txt:42

3. Read the output PO with libgettextpo again. po_message_filepos() interprets
the file references as (two references instead of one): [{abc.txt/de -1}
{f.txt 42}]
