filelist/*: use "searching" instead of "including" in top-level msg

When this is printed, it's about to search the given path for stuff to
slurp up, but it hasn't actually included anything yet. Using
"Including" here was kinda confusing, so this changes it to use
"Searching for." Hopefully that's better!
