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? ;-)

Fri 30 Sep 2011 07:39:50 PM UTC, original submission:  

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

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"); }

This is not the same command!

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