python 使用Regex合并以引号开头的行

我想合并两行，只有一个换行符\n，有时下一行以引号开始。我尝试使用以下代码来合并它们，用\"查找引号，

comb_nextline = re.sub(r'(?<=[^\.][A-Za-z,-])\n[ ]*(?=[a-zA-Z0-9\(\"])', ' ', txt)

但是对于以引号开头的行不起作用。有没有办法合并以引号开头的行？谢谢！
我的文本如下所示：

import re
 
txt= '''
The first process, called wafer bumping, involves a reflow solder process to form the solder balls on all of the input/output
(I/O) pads on the wafer. Because of the extremely small geometries involved, in some instances this process is best accomplished in a hydrogen atmosphere. RTC offers a high temperature furnace for this application, equipped with the hydrogen package, providing a re-flow process in a 100 hydrogen atmosphere. For a second process, called 
"chip joining", RTC offers both a near infrared or forced convection oven.
'''

comb_nextline = re.sub(r'(?<=[^\.][A-Za-z,-])\n[ ]*(?=[a-zA-Z0-9\(\"])', ' ', txt)
print(comb_nextline)

我希望能得到这个

也可以在匹配换行符之前匹配可选空格

(?<=[^.][A-Za-z,-]) *\n *(?=[a-zA-Z0-9(\"])

Regex demo|Python demo
或者使用取反字符类[^\S\n]匹配所有空格而不使用换行符

(?<=[^.][A-Za-z,-])[^\S\n]*\n[^\S\n]*(?=[a-zA-Z0-9(\"])
