The problem with here-documents has been fixed.

As for the other question, look at $HISTIGNORE and $HISTCONTROL.

Lines with white space char in first position and commands or comments are lost in history to.

A trick or a feature? ;-)

$ gcc -x c - <<EOT
#include <stdio.h>
int main() { printf("hi\n"); }
EOT
$ ./a.out
hi

now use the up cursor, or "fc -2" to return to the gcc command, it has been mangled to:

gcc -x c - <<EOTint main() { printf("hi\n"); }
EOT

This is not the same command!

A # in a here-document is not a shell comment!
