[FYI] {test-protocols} tap/awk: support Solaris /usr/xpg4/bin/awk

[Stefano Lattarini]

* lib/tap-driver.sh: Use `\t', not `\\t', to represent tabulation
character in regexps, even when inside double-quoted strings; that
seems to be more portable to Solaris 10 XPG4 awk.

        tap/awk: support Solaris /usr/bin/nawk
        * lib/tap-driver.sh (close_or_die): Remove, the use of the `close'
        builtin in there was confusing /usr/bin/nawk from Solaris 10 into
