Links anchors are not processed correctly

I use the Markdown module to convert Markdown (from a Github Wiki) to XWiki syntax. While doing so, internal links from the Markdown document aren't converted correctly. The internal links are converted "as is". For Github wiki (and a lot of other markdown implementations) it is assumed that each heading has an anchor, which is the same as the heading, lowercased and spaces replaced by dashes. However, XWiki uses another default anchor scheme: remove all spaces and prepend an "H". The Markdown converter should take this into account.

Input (Markdown):

- [Title one](#title-one)
- [Title two](#title-two)

## Title one
blah blah

## Title two
asdf

Expected output (XWiki):

* [[Title one>>||anchor="HTitleone"]]
* [[Title two>>||anchor="HTitletwo"]]

== Title one ==
blah blah

== Title two ==
asdf

Actual output (XWiki):

* [[Title one>>||anchor="title-one"]]
* [[Title two>>||anchor="title-two"]]

== Title one ==
blah blah

== Title two ==
asdf
