[Svnmerge] svnmerge.py breaks in cron

[Eric Kolve]

I tried running svnmerge.py trunk inside of a cron job and it failed with this:

stty: standard input: Invalid argument


I traced it back to this block of code:

    # Parse the output of stty -a
    out = os.popen("stty -a").read()
    m = re.search(r"columns (\d+);", out)
    if m:
        return int(m.group(1))

I think the best thing might be to check if the TERM environment var
is set before attempting this.
