Commits: 9e5dcf54 by Andrew McCreight at 2023-01-30T18:59:35+01:00 Bug 1799982 - Remove uses of inline flags from XPIDL regexps. r=xpcom-reviewers,kmag a=RyanVM

Apparently the use of these is being turned into an error in Python 3.11. Fortunately, our uses appears to be rather trivial.

For t_multilinecomment and t_LCDATA, I dropped the (?s) flag and just replaced the one use of . with (\n|.). (?s) means DOTALL, which means that dot includes any character, including a newline. Otherwise it means dot includes any character except a newline.

I took the new t_singlelinecomment from IPDL's parser.py, so I assume it is reasonable enough. t_multilinecomment is also now the same as in IPDL.
