I've added the options --min-age=SECONDS and --max-age=SECONDS to allow
rsync to skip files based on how recently they were modified.
Setting --min-age=30 (for example) would cause rsync to skip files that
had been modified within the last 30 seconds.
Setting --max-age=7776000 would cause rsync to skip files that had been
modified more than 90 days ago (7776000 == 60*60*24*90).
I realize some of this could be achieved with a find command and
--exclude-from, but the same could be said for --min-size/--max-size.
But it's more convenient to have these options, and they would allow for
things --exclude-from wouldn't. For example, a file might've been
modified after generating the exclude file, so rsync would still
transfer it even though that wasn't what was wanted.

By default rsync limits an individual malloc/realloc to about 1GB
in size.
