Hi,
editing python code, the following code concatenates strings with variables:
"""(beginning-of-form-base \"""" + string1 + """\" \"""" + string2 +
"""\" nil nil nil nil t))))"""
while " + string1 +" is highlighted correctly, " + string2 + " has
string face wrongly.
Also `ppss' falsely indicates being inside a string.
BTW everything is fine with an alternative coding using
singlequotes:
"""(beginning-of-form-base \"""" + string1 + '\" \"' + string2 + """\"
nil nil nil nil t))))"""
The bug however exists.
Thanks all
Andreas

Thanks. Indeed backslashes weren't recognized properly in this case.
I've installed the patch below in the emacs-23 branch, which seems to
fix this problem.
