The man page tells me that the header section of the input file will print
the map title and location (if known) centered above the map if there is no
file specified. When I specify a file the header is printed left-justified.
Is there a way to have the header centered when the text file is
specified?

correct.

use the spacebar a lot? 
or use the 'text' instruction instead with y% as -5% or 105% or so..
looking in the ps.map/do_header.c source code there is in fact a lot
of rather interesting & undocumented formatting magic available.
(I looked because there's often a lot of old p.map goodies lurking about
in there waiting to be discovered)
%% - literal %
%n - ??? newline
%_ - horizontal bar
%d - date
%l - location name
%L - Location's text description
%c - "<%s> in mapset <%s>"
%m - mapset name
%u - user name
%x - mask info
%- - proceed to this char column number (? see example)
and example is given in the GRASS 5 source code:
grass-5.4.1/src/paint/Programs/p.map/cmd/HEADER
%_
LOCATION: %-27l DATE: %d
MAPSET: %-27m USER: %u
RASTER MAP: %c
MASK: %x
%_
Produced by: US Army CERL, Champaign Illinois
Software: GRASS
%_
I've now added this to the ps.map help page.
if anyone has a better idea how %n and %- should work, please post.
I expect for %-#x you will want to use a fixed-width font..
