Is this accurate? It was true before my commit d71f9264 which enabled .MT and
.UR to be hyperlinks (both of which used diversions) and provided a means to
"bracket" the resulting text as a hotspot. Maybe the mechanism of using the
pipe character to "open" the bracket needs further promulgation, or perhaps we
should add a pair of macros to pdf.tmac, something like:-

.de pdflinkstart
.  ds pdf:col \\n[.m]
.  pdfhref \\$1 -D \\$2 "|"
..
.
.de pdflinkend
.  nop \X'pdf: markend'\m[\\*[pdf:col]]\c
..

Which could be used as:-

.pdflinkstart W http://bbc.co.uk
.nf
A multi
line hotlink (possibly from a diversion)
.fi
.pdflinkend

Just a thought.
