Get 1992/lush to work with gcc - won't with clang

I used a patch from Yusuke Endoh to get it to work with gcc. Due to the
different messages with different compilers it's expected that this
won't work with every compiler.

I provided a 'runme.sh' script to run the command in the correct way.

I made the entry use fgets() not gets().

I updated bugs.md pointing out that it does not work with clang and
alternative code is welcome.

+work with gcc. Thank you Yusuke! [Cody Boone
+Ferguson](/winners.html#Cody_Boone_Ferguson) made it use `fgets()` instead of
+`gets()` and also added the `runme.sh` script to demonstrate it (using make was
+problematic). Cody notes that unfortunately this does not work with clang due to
+different compiler messages.
