Subject: [PATCH] Revert "core syntax: strip the path from filename on
 syntax.get (#1168)" (#1322)

* Revert "core syntax: strip the path from filename on syntax.get (#1168)"

This reverts commit af6c4bc152234e13f3e12819e361e1b92a387013.

The previous behavior was correct and allowed access to the full path for path-dependant syntaxes.

* Use `Doc.abs_filename` to obtain syntax when possible

This allows matching full paths in language syntaxes, but we lose the
possibility of matching the project root.
