After #5151, some iref links are broken or unsightly where the iref parameter list extends across a line break; for example,

an expression is converted (either implicitly or explicitly) to type T ([conv], [expr.type.conv], [ expr.dynamic.cast], [expr.static.cast], [expr.cast]), or

and

the operand of a cast or conversion ([conv.integral], [ expr.type.conv], [expr.static.cast], [expr.cast]) to an unsigned ordinary character type or std​::​byte type ([cstddef.syn]), or

In the first case, the iref to expr.dynamic.cast has unsightly extra space but the link works, but in the second case the link to expr.type.conv is itself broken, having extra spaces within the link target, probably because the second case is indented.
