bug#10172: 24.0.92; compile-tests.el failure

[Chong Yidong]

With latest trunk, `make check' fails with:

1 unexpected results:
   FAILED  compile-test-error-regexps

>From further debugging, the columns reported by compilation-parse-errors
are now off by one.  Did the latest changes to compile.el switch the
column numbers from being 0-indexed to 1-indexed?
