Subject: Removed dead code.
X-Git-Tag: 0.15~372
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=d36af2c84f60ad45a3be750767c49e55dae7e2a8;p=re2c

Removed dead code.

Used 'if (next) assert(next->label == from->label + 1);'
to ensure that code is really dead (and 'next' is always
the next state to 'from').
