Feature request: leave A tags with in-page targets (# sign) as is

[Pierric82]

This comes from a wallabag use case (see here for context). This probably applies to other use cases in RSS readers.

Currently for pages with footnotes, where links typically will be to #something, the full original URL is inserted when the article is saved. In other words, the link is changed from #something to https://website.com/article#something. This means that clicking the link in wallabag opens the original article. However, the name attribute of A tags is preserved, so if the link was saved as #something without modification, I believe one could navigate to/from the footnotes without changing pages.

Therefore I'd suggest ensuring that A tags with href starting with a hash sign # do not get transformed to include the original URL, but instead are left untouched.
