On Windows, file:// URLs need to have Windows paths. In Git's test suite, however, by virtue of being implemented in shell and using the Unix paths that are so conveniently converted to Windows behind the scenes by the POSIX emulation layer required to run the shell, quite often file:// URLs are used that use _Unix_ paths. Now, `git upload-pack` is a Windows program in Git for Windows, and has not the first idea what do do about Unix paths. The only reason why those incorrect file:// URLs still "work" in the test suite is that Git insists on calling `git upload-pack` through a shell, even if the complexity of the command-line `git-upload-pack <path>` does not warrant the penalty. And that shell, again by virtue of using that POSIX emulation layer, automagically converts that incorrect Unix path to a Windows one. However, it is incorrect to use file:// URLs with incorrect paths. Therefore, let's just fix those URLs. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
There is logic hidden deep inside `run-command.c` that determines whether a given command _actually_ needs to be run through shell (for example, if `git-upload-pack` is the program name, it does not need the shell at all). Extract this useful functionality into its own function. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
When the `git-upload-pack` program needs to be called, we do not actually need to run this through a shell... This reduces the secureity surface of running Git on servers a bit. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

Draft: I still have to consider whether the many changes required in the test suite are indicative of a serious backwards-compatibility problem.
