feature request: only set RT when RS is found

[Ole Petter R?nningen]

Hi

I am sure this has been discussed many times, yet my google-fu has failed to 
come up with some rationale.

As you know, gawk sets the variable RT to whatever matches RS, if RS is a 
regex. If EOF is reached mid-line and RS is therefore not matched, the record 
is terminated but RT is NOT set. This is a good way to detect possible "partial 
lines", for example when processing through a live log-file.

My proposal is that this behaviour is extended to include the case when RS is a 
single character such as '\n'. If RS is not found, it should IMHO not be 
signalled as found by setting RT.

Thank you,
Ole
