This is yet another change to the regular expressions in crashlog.py that fix a few edge cases, and attempt to improve the readability quite a bit in the process. My last change to support spaces in filenames introduced a bug that caused the version/archspec field to be parsed as part of the image name. So in `0x1111111 - 0x22222 +MyApp Pro arm64 <01234>`, the name of the image was recognized as `MyApp Pro arm64` instead of `MyApp Pro` with a "version" of `arm64`. The bugfix makes the space following an optional field mandatory *inside* the optional group. rdar://problem/56883435 https://reviews.llvm.org/D69871 Files: lldb/examples/python/crashlog.py lldb/test/Shell/Python/crashlog.test
