In this fragment of a troff document build on FreeBSD 10.0-current with pic z.1 |eqn|groff -mm > z.ps
I have a multi-line caption: .DS CB .PIC -C rep-peeq-srf.ps 5.0 .FG "Equivalent plastic strain ahead of the notch (if any) for all models at $-196 sup{0}$C at the surface at $epsilon sub{p} = 0.2%$ or shortly after." "" 0 fig:peeq-srf .SETR fig:peeq-srf .DE which I'd like to break into several shorter lines, but this doesn't seem to work: .DS CB .PIC -C rep-peeq-srf.ps 5.0 .FG "Equivalent plastic strain ahead\ of the notch (if any) for all models at\ $-196 sup{0}$C at the surface at\ $epsilon sub{p} = 0.2%$ or shortly after."\ "" 0 fig:peeq-srf .SETR fig:peeq-srf .DE It results in a mangled caption. The maths are reproduced, but there are lots of gibberish too. I can upload the resulting postscript to illustrate the problem, but perhaps this is a known issue? Thanks Anton i
