fetch saves the manifest as index.mf at the top of the tree and refuses a
manifest that lists a file there. gen given --output, and freshen with its
manifest outside the base directory, listed such a file, so they wrote
manifests fetch would not take.
Both now leave out each file the manifest would list as index.mf: one at
the top of the tree, or a file given to gen by that name. The rule goes by
that path alone and looks up no file, so a symlink named index.mf never
hides the file it points to. index.mf in a subdirectory is still listed.
The scanner in package mfer gets an option to leave out files by the path
they would be listed by.
Model: opus-5-5
Opening a named pipe that has no writer blocks, so gen and freshen hung
on a tree holding one, and check hung on a listed path that is a pipe on
disk. gen and freshen now list regular files only (with
--follow-symlinks, what a symlink points to must be one) and name what
they skip with -v. check reports a listed path that is not a regular
file as an error without opening it, and its search for extra files
leaves out pipes, sockets and devices.
Judgement call: the pipe tests build on unix only, where syscall.Mkfifo
exists.
Unverified: sockets and devices are not tested; the tests use pipes.
