[perl #128302] split docs don't mention pattern modifiers

This is a bug report for perl from Smylers@stripey.com,
generated with the help of perlbug 1.40 running under perl 5.25.2.


-----------------------------------------------------------------
perldoc -f split doesn't state that split /PATTERN/ can use pattern
modifier flags, but it seems that it can:

  ./perl -Ilib -E 'say foreach split /a b # c/, q[0aB1a b # c2a B # c 3]'
  0aB1
  2a B # c 3

  ./perl -Ilib -E 'say foreach split /a b # c/ix, q[0aB1a b # c2a B # c 3]'
  0
  1a b # c2a B # c 3

This should be included in split's documention.

Are all the qr/PATTERN/ flags also valid on split? (With the already
documented exception that /^/ implies /^/m anyway.)
