The base path being optional in the Caddyfile is convenient when you just want the whole site to be markdown-enabled. The other change is to always generate links... this is because an index page for markdown files may not be statically generated, but it should still show links. Commit 09341fc was a regression, and this fixes it.
Most of the Windows test failures are due to the path separator not being "/". The general approach I took here was to keep paths in "URL form" (ie using "/" separators) as much as possible, and only convert to native paths when we attempt to open a file. This will allow the most consistency between different host OS. For example, data structures that store paths still store them with "/" delimiters. Functions that accepted paths as input and return them as outputs still use "/".
There are still a few test failures that need to be sorted out.
- config/setup/TestRoot (I hear this has already been fixed by someone else)
- middleware/basicauth/TestBrowseTemplate and middleware/templates/Test (a line endings issue that I'm still working through)
* As value mutex was copied and therefore synchronization worked wrong
* It's pretty big structure with reference types, so copying create unnecessary
pressure on GC
