No idea how to use mawk to emulate the behavior you describe; it
is far from being gawk.  However you can refine something
looking like that, to /not/ make use of gawk:

	grep -A1 -E "\<${pattern}\>" \
	| tail -n-1 \
	| mawk '{print $2}'

I get the following, if this is what you expect:

	$ pattern=try grep -A1 -E "\<${pattern}\>" | tail -n-1 | mawk '{print $2}'
	Host try
	IdentityFile ~/.ssh/try/id_rsa^D

Feels a bit like Wily the coyote maybe, I'm pretty much certain
it can be done simpler...  :-)
