annotate command fails to annotate many files

I just upgraded to the latest version of the coverage module. We have
a reasonably complex installation of internal Python modules at work.
I made a long test run overnight and this morning asked for a coverage
report. It looked fine:

    Name                                                                                                 Stmts   Exec  Cover

Then I asked it to generate annotated listings:

    % coverage annotate -d cover

Looking in my cover directory I only saw one file:

    % ls -l cover
    total 75
    -rw-rw-r-- 1 skipm snake 76230 Mar 18 09:15
    Indicators_rigel_takeover.py,cover

How do I get it to generate coverage output for the other 240+ modules?

I figured out what was preventing annotation. In AnnotateReport.annotate_file it
explicitly checks to see if a file is not a relative path. Commenting out that check
makes things work for me.

I'm not sure what the ultimate solution is, but simply considering files absolute
paths as uninteresting seems to be too blunt an instrument.

I just hit a similar issue with the same solution. Not sure why annotate depends on the code unit being a relative path??

annotate.annotate_file: line 50

coverage version, 3.4

Please note, I experienced this by using the API calls directly for annotate and html output:

#!python

        tmp_dir = os.path.join(coverage_base_dir_new, "annotated_text")
        self.coverage.annotate(morfs = self.modules,
                                  directory = tmp_dir,
                                  ignore_errors = False,
                                  omit = self.omit_list)
        tmp_dir = os.path.join(coverage_base_dir_new, "annotated_html")
        self.coverage.html_report(morfs = self.modules,
                                  directory = tmp_dir,
                                  ignore_errors = False,
                                  omit = self.omit_list)

Same calls, same data, annotate returns nothing and html returns it all.
