This affects Git HEAD, not any released version of _groff_.
$ ~/groff-HEAD/bin/nroff -man <<EOF
.TH foo 1 2025-01-04 "groff test suite"
.SH Name
foo \- frobnicate a bar
.SH
Description
With any luck,
this text is visible.
EOF
foo(1) General Commands Manual
foo(1)
Name
foo - frobnicate a bar
groff test suite 2025‐01‐04
foo(1)
Not only is text missing, but the right-hand footer gets rendered in the wrong
typeface because enough of `SH` was processed to remap the `B` font to `BI`.
The problem is a missing `\}`. Fix pending.
At least I can say I've finally, after ~7-8 years of contributing to _groff_,
seen a man page in the wild that consciously exercises `SH`'s input trap--it's
GNU _dc_(1).
`SS` does not suffer the defect. But I'm adding a regression test for it
anyway.
