The warnings are correct!  Due to the many `\ ' which insert
unpaddable whitespace groff indeed can't adjust the line.  The right
way to achieve the desired effect is to use .nf and .fi instead:

----------------------------------------------------------------------

.TS
expand box;
c c
l lw(3.5i).
Escape  Description
_
T{
\f[C]\\v\fP '\f[I]distance'\fP
T}  T{
.nf
Move \f[I]distance\fP vertically down the page.  Precede \f[I]distance\fP
with a minus sign to move back up the page.
.fi
T}
T{
\f[C]\\h\fP '\f[I]distance'\fP
T}  T{
.nf
Move \f[I]distance\fP horizontally to the right.  Precede \f[I]distance\fP
with a minus sign to move back to the left.
.fi
T}
.TE

----------------------------------------------------------------------

All warnings are gone.

Personally, I would prefer to use .na and .ad instead to produce
ragged-right text and to avoid dependency on the actual text width of
the document, but this is a minor issue since the width is already
specified.
