GNU ed version 0.2, signal handling bug

I use GNU ed version 0.2 on a GNU/Linux system and I
think I found a bug in the signal handling.

The interrupt character, which should interrupt
current executing command, correcly triggers the
SIGINT handler once, while all successive interrupt
characters are ignored EQU they don't trigger the
signal.c:signal_int() function anymore.

To reproduce the problem: press interrupt character
more than once on the ed command line.

Please excuse me if I missed something trivial.
