Use '' quotes instead of `' to delimit names of files and packages in
warning and error messages, because it is easier to cut-n-paste name in
question that way (single click) without confusing the shell. And yes,
I know that it is less eye-candy...

When reading the code I had to stop, say "ok, what does *these*
modifications of strl*() do? Pull out grep. Oh, not in add/, maybe above
in ../lib/? Yep. So what do they do? Comments above them are misleading,
guess I'll have to read the code. Oh, they just test strl* against the
size and return the result of the test. Now I can continue to read the
code I was.
The uses of s_strl*() then test that result and errx()'s.
Lets think about the "optimized" code I am removing:
In general the compiler pushes the three args to strl* onto the stack and calls
s_strl*. s_strl* has to indirectly access 3 args from the stack. Then push
them on the stack a 2nd time for the real strl* call. s_strl* then pops the
return from strl* off the stack; or moves it from the register it was returned
in, to the register where tests can happen. s_strl* then pops the three
arguments to strl*. Perform the test, push the result of the test, or move it
from the result register to the return value register. The caller to s_strl*
now has to either pop the return value of s_strl* or move it from the return
value register to the test register. The caller then pops the three args to
s_strl* off the stack (the same args that s_strl* itself had to pop off after
the real call to strl*). The s_strl* caller then performs a simular test to
what has already been done, and conditionally jumps. By doing things this way, we've given the compiler optimizer less to work with.
Also, please don't forget the that call to s_strl* has possibly jumped to code
not in the cache due to being far away from the calling code, thus causing a
pipeline stall.
So where is the "optimization" from s_strl*?
It isn't code clarity.
It isn't code execution speed. It isn't code size either.
warnx()+exit() with errx() and replace a big if..then..else construct

/usr/X11R6/bin should be there. This helps all the ports that need to
run `mkfontdir' and error out as many port maintainers do not realize
`mkfontdir' isn't in the path.

Switch from [r]index() to str[r]chr() functions, which are more ISO

Also, add a cross reference to pkg_info(1) in pkg_version(1). Finally,
in pkg_version(1), don't put a period at the end of the list of see also
