libyaml refuses all strings starting with '%'

In my previous mail I indicated a problem with a string consisting of just
one percent sign. Actually the same problem with libyaml (as opposed to Syck)
occurs for _all_ strings _starting_ with a percent sign.

(I urgently need to know whether this is a bug in libyaml or whether I am
writing incorrect YAML. My production files are full of entries like "format: %4i")
