The code in question is:

          if (strcmp(answer,"list") == 0) {
            if (isatty(1)) {
	      sprintf(buff,"$GRASS_PAGER %s",Tmp_file);
            }
            else
	      sprintf(buff,"cat %s",Tmp_file);
            system(buff);
          }

Tmp_file is the name of a file which should have been created by
G_tempfile(). This function creates temporary files using the pattern:

	<gisdbase>/<location>/<mapset>/.tmp/<hostname>/<pid>.<count>

First, check whether the file in question exists. The file will be
deleted when the projection request is completed or aborted, so you
need to look for it while at the second "Enter list ..." prompt.

If the file exists, then there would seem to be a problem with the
program which is specified by the environment variable GRASS_PAGER. 
This defaults to "more" if /bin/more exists and is executable, and
"less" otherwise.

If the file doesn't exist, check whether any similar file exists.
