Modified files:
	usr.bin/awk    : awk.1 

Log message:
document various aspects of awk behaviour:

- when newlines are permissible
- effects of null RS
- $NF can be used to find value of last field
- -F [ ] can be used to set FS to a single space
- t and \t are synonyms when used with FS. use [t] for a literal `t'.
- make [prog | -f profile] optional again in SYNOPSIS

Also move the functions to the end of the page for a more logical layout.
