[PATCH] hg-to-git: fix parent analysis

[Stelian Pop]

Fix a bug in the hg-to-git convertor introduced by commit
1bc7c13af9f936aa80893100120b542338a10bf4: when searching the changeset
parents, 'hg log' returns an extra space at the end of the line, which
confuses the .split(' ') based tokenizer:

    Traceback (most recent call last):
      File "hg-to-git.py", line 123, in <module>
          hgchildren[mparent] += ( str(cset), )
      KeyError: ''

If it's not already too late, you could wrap this line when you're
changing it anyway. Something like this maybe:

    prnts = os.popen('hg log -r %d --template "{parents}"' % cset
                     ).read().strip().split(' ')
