Regexp group number show wrong

[nuintun]

Here is a regexp:

(@import\s+url\s*\(.+?\);?|@import\s+(['"]).+?\2;?)

the right group number will be:

but in regexper:

[javallone]

This bug actually went back to some rework I did before the site was even launched (it was caused by e362a54 for the curious). I'm amazed it has been around this long.

Thank you very much for catching and reporting it!
