ed: Move modflag=0 to clearundo()
...
When we discard the content of an undo buffer
is because we don't need it anymore, and it means
that we don't care about the modify state of the buffer
so we can reset the modflag in clearundo(), and
remove this assignation each time clearundo() is called.

call to addpre() in every iteration of subline()
...
It is needed to call to addpre(), because in other
case the prefix of all the occurrences before
the target will not be copied to the result
string.

Escape correctly characters in getrhs()
...
getrhs() must remove \ excepts in the case of & and \d
(where d is a digit), because in this case are sequences
understood by addsub(), so addsub() must be able to see
them.

getrhs() must not interpret escapes, because in other case
addsub() will not be able to see the escaped characters.
