main: revise mgroup regex flag

Open masatake opened this issue 4 years ago • 1 comments

  • It seeems that the initial value for the flag can crash ctags.
  • The range of the value passed to the flag is not verified well.

Thank you very much for pointing out this. I found a critical bug in the code about mgroup. I will fix.

docs/optlib.rst must be updated when fixing this issue.
