vac, unvac: allow 128MB cache size, up from 4MB
When a directory has lots of children, vac crashes because it runs out of cache. Fixes #266.
Trivial changes: whitespace and modes.
Remote whitespace at the ends of lines. Remove blank lines from the ends of files. Change modes on source files so that they are not executable. Signed-off-by: Dan Cross <cross@gajendra.net>
