ed documentation feedback: accessibility, clarity, and a typing mistake

[David Apps]

I hope that you are well.

Thank you for your work on this software.

I have some feedback about the pages at the following addresses:

http://www.gnu.org/software/ed/

This page includes a link with the name "here". Please use descriptive 
names for your links to help accessibility.

http://www.gnu.org/software/ed/manual/ed_manual.html

"A null re is equivalent to the last re encountered."
At this point, this section of the manual has not defined "re". You 
might help some readers by defining "re" or using "regular expression" 
until you do so.

"additonal"
should probably be
"additional"

Please consider using a spell check facility to help find mistakes like 
this.

Thank you.

David
