Conda module: directory truncation does not work on Windows

[dr-eme]

Bug Report

Current Behavior

Even if path truncation is activated, it is not applied, and thus environments created via conda create -p [path] are shown with full path.

Expected Behavior

Truncation should be OS aware (similar to what directory module does when use_os_path_sep = true).

Possible Solution

Truncation function used in module shall accept separator character.
Alternatively, allow applying string replacements to variables in configuration.
