Surely ignoring blank lines is going to be less irritating.

However you like.  Make a variable which contains your regexp.  If you
have a string in a scalar and want a regexp which matches that string
you can do this:
   my $regexp = $string;
   $regexp =~ s/\W/\\$&/g;
   ... m/^$regexp/ ...

True.
