Whatis occasionally won't find in summary lines after commands
containing underscores.
Example: (this example is actually from SunOS 4.0, though the bug is
also in 4.3bsd man)
% whatis perror
perror, sys_errlist, sys_nerr, errno (3) - system error messages
% whatis errno
man: man entry for errno not found.
Fix:
590c590
< while (isalpha(*bp) || isdigit(*bp))
---
> while (isalpha(*bp) || isdigit(*bp) || (*bp == '_'))
