I wonder if the `\:' looks like it is at the start of the word `blrphl',
in your example, and thus says to not hyphenate `blrphl' rather than
provide a break point for hyphenating `mrphl\|blrphl'.

    $ cat breakspace.tr
    .pl 15
    .ll 1c
    A b c d e f g
    .br
    A b c\0d\0e f g
    .br
    A b c\0d\:\0e f g
    .br
    A b c\0d\0\:e f g
    .br
    A b c\h'1n'd\&\h'1n'\&e f g
    $ 
    $ groff -a breakspace.tr
    <beginning of page>
    A b c
    d e f g
    A b
    breakspace.tr:5: warning [p 1, 0.5i]: cannot adjust line
