Uh, I know I'm stating the obvious, but you might try these 2
techniques to enhance your diff experience:
1. Use "diff -w".
2. Do "cat filename | sort > filename.sorted" for both files you are
diffing, and then compare both sorted files.

I keep bumping up against this, so I thought I'd throw this question out
to those who understand sed better than I do.
What I'm trying to do is to clean up the contents of some files
(/sys/i386/conf/GENERIC would be a good example) to get more readable
diffs. To that end, I'm trying to use sed to

Not directly FreeBSD question, however. Is it possible with sed (or awk)
to turn this:
i/in/1 2/3 4 5 6
into
i/in/1 2/3456
The same syntax would also need to work on:
i/in/1 2/x y z (result would be i/in/1 2/xyz)
i/in/1 2 (result would be i/in/12)
The closest I have gotten it to is:

A script of the form:
echo abc | sed -e 's,b,\
,'
will work if the newline is escaped with a backslash and the remainder of
the sed substitute is on the next line.
