--------------------------------------------------------------
yes, thank you Milos for this testcase: I still didn't have time to work on it,
but such test case is absolutely necessary to have a chance to fix the bug
the edge case is related to the added {{H}} in {{6.1H.5-beta}}, in the middle
of the version string instead of appended to the end: that's the unusual part,
and I know there is some tweak in the parsing algorithm for transforming {{1H}}
into a canonical representation: IIRC, the canonical representation is {{1-H}}
and I suppose it's coupled with the fact that {{6.1.0}} is equivalent to {{6.1}}
I'll have a look at the test case this WE to narrow the problem (can't tell if
it will be sufficient to have a fix...)
