Where in the man page are you proposing adding it? But I already see
this in 'man sed':
s/regexp/replacement/
Attempt to match regexp against the pattern space. If
successâ
ful, replace that portion matched with replacement.
where the "replace that portion matched" implies that the portion not
matched is preserved unchanged.
