[PATCH] AT_TESTED: fix regression in word splitting

[Eric Blake]

Regression introduced in commit 851ef51.

* lib/autotest/general.m4 (AT_TESTED): Rework loop to quote each
element, not the entire argument.
---

This appears to fix the problem (when given AT_TESTED([autoconf automake]),
we were adding "autoconf automake" instead of "autoconf" "automake" to
the list of unique programs), but I'd appreciate an ACK from Paolo to make
sure I didn't break the $EXEEXT handling in the process.
