And it added a trailing newline to $aux_dir. What's worse is the
testsuite did not catch it; but trying to autoreconf on cygwin 1.5 did
(where newlines are not permitted in file names by default):

Sorry for not spotting it sooner.

The difference is subtle. The call to $traces->getline preserves the line
separator from the trace file, even though it wasn't part of the macro
argument. In the old code, the regex then stripped that newline before
creating $1 and assigning to $aux_dir; but in the new code, $args[0]
contains the remainder of the line from the split including the newline.
Here's what I'm pushing, if it passes a testsuite run.
