help with adjusting a regex for issue github#946

[Jérémy Prego]

hello,

in order to regain the comfort I had before orca decided to remove the 
MultiCase, I decided to create a regex to handle this case, but I'm 
still left with a few side effects

currently, I've come to this:
complexSymbols:
separateCapital    ([A-Z]*?[a-z]{1,})([A-Z]{1,}[a-z]*?\b)

symbols:
separateCapital    \1 \2    none


to keep things simple, you generally have to separate the different 
boxes so that the word is pronounced correctly. for example: OpenSMTPD 
should become open SMTPD

My problem is that in such a case, if there is a "." or a "," after 
openSMTPD, the characters are pronounced literally, instead of being 
paused.

I have tested many things, such as
complexSymbols:
separateCapital    ([A-Z]*?[a-z]{1,})([A-Z]{1,}[a-z]*?\b)([,.]?)

symbols:
separateCapital    \1 \2\3    none

in this last example, it's a bit better since the "." and the "," do 
indeed make their pause, but they also do it in the case of a url for 
example openSMTPD.toto.com whereas I'd like to hear openSMTPD [dot] toto 
[dot] com

as I still have a lot to learn about regex, I'd like a little help, if 
what I want to do is possible in regex. :)

Thank,

Jeremyp3 :)
