Add 1995/leo/try.sh and update bugs.md

There appears to be a bug where the program blocks. In one case another
command makes it work but the judges remarks suggest one way and it does
not. The other command does not seem to work at all, even if used like
the workaround with the first one.

Updated make clobber to remove foo.ps.

Updated .gitignore.

+### STATUS: known bug - please help us fix
+### Source code: [1995/leo/leo.c](1995/leo/leo.c)
+### Information: [1995/leo/README.md](1995/leo/README.md)
+
+The judges suggested that the following commands should result in output:
+
+
+```sh
+./leo 1 | cat - /dev/tty | gs -
+
+./leo 37 80 | cat - /dev/tty | gs -
+```
+
+The first one can work if one does instead:
+
+```sh
+echo "" | ./leo 1 > foo.ps
+gs foo.ps
+```
+
+but it is supposed to work in the pipeline as is. The second one does not appear
+to work at all even if one redirects to a file (like the workaround for the
+first) as it appears to just block.
+
+It is not known if this is platform specific but this was observed in macOS and
+it would be good if it was fixed.
