If you try to parse the following command:
suser=expr "\id`" : '(uid=0)(.) .'`
this will fail with the following exception:
bashlex.tokenizer.MatchedPairError: unexpected EOF while looking for matching '"' (position 7)
After some investigation, it was found to be the adjustment made when a backquote is found within the function '_stringextract' in module 'subst.py', it will incorrectly only skip the backquote itself, not the following character as well.
The simple solution is to increment the variable by 2 instead of 1, this will then handle the parsing correctly.
