# test adding a file by relative path from the repo root, when the cwd is

# suite.

# The case below makes the R4 case (of using a repo-root-relative path in a
# subdir of the repo) look even more like the R5 case (of using a
# repo-root-relative path outside the repo) by usign the --repo flag. It still
# failed on darcs 2.4.

# is a subdir of the repo root. In this case the path relative to the repo root
