I believe that the browse function you request for GNU ed already
exists. We just use the letter `z' instead of `b'. Syntax appears
to be the same. From the manual:
(.+1)zn Scrolls n lines at a time starting at addressed line. If n is
not specified, then the current window size is used. The cur-
rent address is set to the last line printed.
The z command is recognized by some older UNIX programs where paging
makes sense - e.g., to scan message headers in mail(1).
Mnemonic: z is scroll-shaped (also, the last letter you'd think to
use for browsing/paging...)

PS - GNU ed has a paging misfeature that has been removed in the upcoming
release.
PPS - There is an upcoming release.
