[Groff] line break question

[Joerg van den Hoff]

I noticed that groff might format something like


".... some_text(more_text) ...."


in such a way that it comes out as

".... some_text("
"more_text) ...."

in other words, although there is no space after the opening parenthesis, the
latter is treated as the word ending.

question: is this intended or a bug? is their a straightforward way
to enforce treatment as a single word?

remark: I would argue that only white space (and possibly dashes?)
should be treated as a word ending. or formulated differently: not every
parenthesis should be treated as a word start.

caveat: I know that usually there should be a blank in front of the parenthesis.
in my case the problem occurs in a bibliography where the above is examplified
by

"Radiology(239(3))"

and this is the way it comes out of `refer' in the citation style used and 


"....Radiology("
"239(3)) ...."

looks bad...
