subrepo: make "_sanitize()" work
"_sanitize()" was introduced by 224e96078708 on "stable" branch, but
it has done nothing for sanitizing since 224e96078708.
"_sanitize()" assumes "Visitor" design pattern:
"os.walk()" should invoke specified function ("v" in this case)
for each directory elements under specified path
but "os.walk()" assumes "Iterator" design pattern:
callers of it should drive loop to scan each directory elements
under specified path by themselves with the returned generator
object
Because of this mismatching, "_sanitize()" just discards the generator
object returned by "os.walk()" and does nothing for sanitizing.
This patch makes "_sanitize()" work.
This patch also changes the format of warning message to show each
unlinked files, for multiple appearances of "potentially hostile
.hg/hgrc".

This is useful to test local and uncommitted changes in an otherwise-clean source tree. This means that purge will delete: - Unknown files: files marked with "?" by :hg:`status` - Empty directories: in fact Mercurial ignores directories unless they contain files under source control management But it will leave untouched: - Modified and unmodified tracked files - Ignored files (unless --all is specified) - New files added to the repository (with :hg:`add`) If directories are given on the command line, only files in these directories are considered. Be careful with purge, as you could irreversibly delete some files you forgot to add to the repository. If you only want to print the list of files that this program would delete, use the --print option.
