annotate -i doesn't work

According to the help output, the annotate command should ignore errors when reading source files if the -i option is specified. However, it doesn't do so for me when it fails reading a doctest file, but simply stops creating annotations at that points. The report command, however, does ignore the same error if given -i.

Can you provide me with a simple example?

Sorry about the delay... here it is: The problem doesn't occur with a doc-test file that is being run by doctest's basic API (such as doctest.testfile('readme.txt')). It does, however, occur when using the unittest API:

========================================================================

$ cat readme.txt
This is a doc test:

print 'foo'
foo

$ cat test.py
import doctest
import unittest

suite = doctest.DocFileSuite('readme.txt')
runner = unittest.TextTestRunner()
runner.run(suite)

$ coverage run test.py
.

Ran 1 test in 0.002s

OK

$ coverage annotate -i
Couldn't parse '/home/thomas/coverage/readme.txt' as Python source: 'invalid syntax' at line 1

========================================================================

In this case, the parse error occurs despite -i and no coverage reports are written.

I fixed this in <<changeset 9ef11bf7e50d (bb)>> by not tracing the doctest file in the first place.
