Tim, have you tried using /\v to start all regexes in Vim?
That pushes Vim's weird regex dialect closer to POSIX, thus helping
preserve sanity.
Although it isn't explicitly listed in the table at ":h \v", "+" is then
magic, as covered by the help item's initial statement.
It also reduces the number of backslashes in most regexes, I find.
Now if only there were a config switch to make that the norm! ;-)
