yup, I'm ever more confused

oh, I see ... dazed & confused.

really? what about '/inet/' extension?

@Aharon: 

pls see attached diffs, it's just a POC for '/dir/' extension - I 
know it'd be in extension/, likely not portable etc., and likely won't
ever make it into official code - but just for fun and perhaps future ref,
eg:

$./gawk 'BEGIN{r=1
$       while (r==1) {
$           r=getline < "/tmp"; print "r="r" -"$0"- ERRNO=" ERRNO
$         }
$       }'
r=-1 -- ERRNO=Is a directory 

$./gawk 'BEGIN{r=1
$       while (r==1) {
$           r=getline < "/tmp/xrdb.wdm.log"; print "r="r" -"$0"- ERRNO=" ERRNO
$         }
$       }'
r=1 ---help- ERRNO=0
r=1 -- ERRNO=0
r=0 -- ERRNO=0

$./gawk 'BEGIN{r=1
$       while (r==1) {
$           r=getline < "/dir//tmp/rd.c"; print "r="r" -"$0"- ERRNO=" ERRNO
$         }
$       }'
gawk: warning: could not open `/dir//tmp/rd.c', mode `r'
r=-1 -- ERRNO=Not a directory

$./gawk 'BEGIN{r=1
$       while (r==1) {
$           r=getline < "/dir//tmp"; print "r="r" -"$0"- ERRNO=" ERRNO
$         }
$       }'
r=1 -.- ERRNO=0
r=1 -..- ERRNO=0
r=1 -rd- ERRNO=0
r=1 -.clean- ERRNO=0
r=1 -orbit-central- ERRNO=0
r=1 -rd.c- ERRNO=0
r=1 -mc-amsis- ERRNO=0
r=1 -xrdb.wdm.amsis.log- ERRNO=0
r=1 -xrdb.wdm.log- ERRNO=0
r=1 -gconfd-central- ERRNO=0
r=1 -lost+found- ERRNO=0
r=1 -.X11-unix- ERRNO=0
r=1 -.X0-lock- ERRNO=0
r=1 -.font-unix- ERRNO=0
r=1 -xrdb.wdm..log- ERRNO=0
r=1 -hsperfdata_central- ERRNO=0
r=0 -hsperfdata_central- ERRNO=0

not too bad eh? ;-P

weak arguments, if any
