I agree with Julian here. This isn't DOS where we need
to fit filenames in 8.3 characters. There's no reason
to abbreviate that way.

Just out of curiosity I made a small survery on the src tree.
First in src/sys only (this is a RELENG_6 machine):
$ cd /sys
$ find * | awk -F/ '{print length($NF)}' | sucs -k2

As you can see, the maximum of the count graph of filenames'
lengths is at 8 characters. The median is 9, the average is
9.4 chars. 18% of the filenames are 13 characters or longer,
therefore "tcp_offload.[ch]" wouldn't be that unusual at all.
When you look at C source files only ("find * -name \*.c"),
then the average even reaches 10.6.
By the way, "sucs" is an alias: sort | uniq -c | sort -n
(I use that often.)
It's not much different when you look at /usr/src which
includes the 3d party contrib stuff (I grouped some of the
lines for brevity):
$ cd /usr/src
$ find * | awk -F/ '{print length($NF)}' | sucs -k2

The maximum is at 8 again, the median is 9 again, and the
average is 9.7 (just slightly longer than in /sys). When
only looking at C source files, the average is 10.2.
