[issue1208] "hg ci" fails when working directory name is longer than 90 bytes

[Jim Meyering]

New submission from Jim Meyering <list+hg at meyering.net>:

This is using a version of hg built from latest sources a few minutes ago
on a debian unstable system (with python 2.5.2):
    $ hg --version
    Mercurial Distributed SCM (version 1.0.1)
                                   
    $ d=$(perl -e 'print "/tmp/"."x"x86'); \
    mkdir $d && cd $d && hg init && touch f && hg add f && hg ci -m.; \
    rm -rf $d
    adding f
    Traceback (most recent call last):
      File "/usr/bin/hg", line 20, in <module>
        mercurial.dispatch.run()
      File "/var/lib/python-support/python2.5/mercurial/dispatch.py", line 20,
in run
        sys.exit(dispatch(sys.argv[1:]))
      File "/var/lib/python-support/python2.5/mercurial/dispatch.py", line 29,
in dispatch
        return _runcatch(u, args)
      File "/var/lib/python-support/python2.5/mercurial/dispatch.py", line 93,
in _runcatch
        ui.warn(_("abort: %s\n") % inst[1])
    IndexError: tuple index out of range


The above may look contrived, but the underlying bug
caused a new test failure in my vc-dwim package.


Rerunning the failing command with --traceback gives this:

    $ hg --traceback ci -m.
