Investiation complete.  The following comment is in the procps source at
line 1018 of ps/output.c:

// The Open Group Base Specifications Issue 6 (IEEE Std 1003.1, 2004
Edition)
// requires that user and group names print as decimal numbers if there is
// not enough room in the column, so tough luck if you don't like it.
//
// The UNIX and POSIX way to change column width is to rename it:
//      ps -o pid,user=CumbersomeUserNames -o comm
// The easy way is to directly specify the desired width:
//      ps -o pid,user:19,comm
//

There are a few ways to handle this:

1.  Live with it.  :)

2.  Create an alias for the ps format you want to use and specify a
column width you want to use for UID.

3.  Specify a format using the PS_FORMAT environment variable.

4.  Hack the source.  Adding the following code at line 1037 of
ps/output.c works:

(outbuf+max_rightward) = 0;
return max_rightward;
