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".
