Subject: replace doesn't support optional groups
Original description:
textlib.py \(method replaceExcept\) doesn't support optional capturing groups
in regex.
I tried to run replace.py with the following regex: "RISHMI\(T |IM\)?" =>
"RISHMI\1"
when running it on a page containing the following text "SOMETHING RISHMI
SOMETHING"
it crashes with the following error:
textlib.py, line 178, in replaceExcept
match.group\(groupID\) + \
TypeError: coercing to Unicode: need string or buffer, NoneType found
line 178 contains the statement:
replacement = replacement\[:groupMatch.start\(\)\] + \
match.group\(groupID\) + \
replacement\[groupMatch.end\(\):\]
textlib.py should check for match.group\(groupID\) ==None and if so, add here
empty string instead of match.group\(groupID\)
