Thank you. But something is wrong. If content length is larger than lenght
of row, editing only displays last line. Even if I can edit previous line
too, it's not refreshed and I should edit it in blind mode.

Steps to reproduce:

iPXE> set test 1234567890 1234567890 abcdefghijklmnopqrstuvwxyz 1234567890 12345
67890 1234567890 1234567890                                                     
iPXE> echo ${test}                                                              
1234567890 1234567890 abcdefghijklmnopqrstuvwxyz 1234567890 1234567890 123456789
0 1234567890                                                                    
iPXE> read test                                                                 

Now try to backspace 20 charactes and then echo ${test} .

Also editing does not work in one "read" command without predefined text for
multirow content.

Another small problem should be, that breaking (ctrl+c) read command will
clear original content. Consider, if this is an feature or bug. :-)
