Does '=' have a special meaning? #10

See https://github.com/magnumripper/JohnTheRipper/issues/1064

$ rexgen/rexgen '(f|\|x|ph)'
f
|x   <-- expected
ph

$ rexgen/rexgen '(f|\|=|ph)'
f
|   <-- unexpected, missing =
ph

$ rexgen/rexgen '(f|\|\=|ph)'
f
|=
ph

Why do we have to escape the = to get it emitted?

I already had a character class SPECIAL in my lexer, but I forgot to tell him what to do with special characters...
