Very similar to T53023 but for internal links.
Please prevent VE from creating links like [[1970|1970 ]], this makes ugly wikitext which is lot more difficult to maintain than necessary.
Exemple of edit with multiple links like that created:

We already trim whitespace from the start and end of selection when creating a new link annotation (and any other kind of annotation, too). If you really mean to include whitespace in it, you modify the annotation after inserting it.
But this is a different issue. Here's the Parsoid HTML corresponding to * 1970 : ''Les Camisards'' de René Allio in the source:
<ul data-parsoid='{"dsr":[7717,8284,0,0]}'><li data-parsoid='{"dsr":[7717,7757,1,0]}'> 1970<span typeof="mw:Placeholder" data-parsoid='{"src":" ","isDisplayHack":true,"dsr":[7723,7724,null,0]}'> </span>: <i data-parsoid='{"dsr":[7726,7743,2,2]}'>Les Camisards</i> de René Allio</li>
The <span typeof="mw:Placeholder"> gets alienated in VE and thus is not treated as whitespace. Perhaps we should handle in it VE, or perhaps Parsoid should stop emitting those ("isDisplayHack":true indeed). This seems related to the "French spaces" feature in the PHP parser, where it converts : (and similar) to : in order to prevent incorrect line breaking in correctly punctuated French-language text. (This is applied in all languages nevertheless.)
Given these don't occur in the English Wikipedia, I'll drop this from Q3 goals and move to Q4.
Affects spaces preceding ?, :, ;, ! and %, and around guillemet quotes, which are all indeed rare and usually incorrect in other languages.
