Upon program invocation, MSYS converts environment variables containing path-like values from Unix-style to DOS-style under the assumption that the program being invoked understands only DOS-style pathnames. For instance, the Unix-style path /msysgit is translated to c:/msysgit. For test t5560, the path being requested from git-http-backend is specified via environment variable PATH_INFO as a URL path of the form /repo.git/foobar, which git-http-backend combines with GIT_PROJECT_ROOT to determine the actual physical path within the repository. This is a case where MSYS's conversion of the path-like value of PATH_INFO causes harm, for two reasons. First, the resulting converted path, when joined with GIT_PROJECT_ROOT is bogus (for instance, "C:/msysgit/git/t/trash-zzz/C:/msysgit/repo.git/HEAD"). Second, the converted PATH_INFO path is rejected by git-http-backend as an 'alias' due to validation failure on the part of daemon_avoid_alias(). Unfortunately, the standard work-around of doubling the leading slash (i.e. //repo.git/foobar) to suppress MSYS path conversion works only for command-line arguments, but not for environment variables. Consequently, side step the problem by instead passing git-http-backend an already-constructed full path rather than components GIT_PROJECT_ROOT and PATH_INFO.
