I am trying to set regexps to let etags recognize tags from Object
Pascal code. For ex. the following regexp;

/^[[:space:]]*type[[:space:]]+\([^ \t=]+\)/\1/

applied to a type declaration:

type MyType = class(TObject)

matches class MyType. I am now trying to match declarations on
multiple lines, for ex.:

  MyType = class(TObject)

I have tried to put a new line in my regexp and use m modifier in
etags regexp but it doesn't work (emacs 24 & 26.2). When i add a m
modifier to the original regexp which doesn't contain newlines, it
doesn't work anymore.

So how are we supposed to use m modifier?
