In r20482, version detection causes a compile error by returning "" (nothing) as REVISION, breaking rev.cpp.

The command run by determineversion.vbs is this:
"hg log -f -k "(svn r" -l 1 --template "{desc}\n" ../"

When the same command is entered from the command prompt, the following error message is shown:
abort: cannot follow nonexistent file: "."

Removing the -f flag fixes this, so the problem seems to be introduced in r20309

Changing "../" to "--cwd ../" in the command fixes the problem (at least for me), as is done in the attached diff.
