Description of problem: No docs\examples on regex option for flag groups. We want to use this option, but it's unclear what we should input and in what format. Please add help for this.
How does a docs bug get pushed so far to the future? I want to be able to use the features now, can you at least provide the info here, so I can start using it.
It's a perl regex. The format is the same as you would use in a bug search in the "Matches Regular Expression" If you make a bug search using the Custom Search "Flags" "matches regular expression" <regex here> You can experiment with what will be matched. If you give some detail on what you want to do, I can probably provide some examples.
This change is now live. If there are any issues, do not reopen this bug. Instead, you should create a new bug and reference this bug.
