I'm using infect now -- update set_aside_vim

Call infect instead of runtime_append_all_bundles.

Don't do filetype or syntax stuff -- that's handled in sensible.
Only work around backupcopy bug in old vim

The issue I had with vim writing incorrect file attributes was fixed in
7.3.1182. If we're 704 or later, stick with auto.

Use v:version instead of version (easier to find in help).
sub: SearchForAnyLine fixes in searchsavvy
Use prepend and append to build runtimepath

Instead of clobbering the existing value of runtimepath (and assuming it
doesn't change), prepend and append my .vim directories to it.

This is also quite a bit easier to read.
