For many commands/pages (e.g. 'tree', 'diff', 'plain', etc.), the ctx.qry.path argument is interpreted as a path within the "virtual" project directory structure. However, for some other commands (notably 'refs', and the clone-related commands) ctx.qry.path is used in a different context (as a more or less "real" path within the '.git' directory). This patch differentiates between these two usages of ctx.qry.path, by introducing a new variable - ctx.qry.vpath - which is equal to ctx.qry.path in the former case, and NULL in the latter. This will become useful in future patches when we want various pages and the links between them to preserve existing in-project paths.
