[9fans] prof, libc, and fixed length fields

[Pietro Gagliardi]

Bentley: /n/sources/contrib/pietro/bentley.bundle
Bentley profiler output (on test program in bundle): /n/sources/ 
contrib/pietro/bentley.profout

It demonstrates two deficiencies of the prof program as is:
- line 312 should be modified to add a space after the first format,  
so that clobbering doesn't happen
- there should be some way to keep static (and some public) library  
routines out of the profile

When my program runs, the last line is
        1 Prof errors
Could this be the cause?
