The file is for a deliberate torture test of color handling and tab
expansion, so pardon the ugliness, it's the point of it. But it's
working here, tho the first part of my 'measuring string' is cut off for
some reason. I don't like this, I hate it, it's dangerous. Don't tell
me it sux, I know it sux. But I would like some way of performing
expansions inside a file without any gottchas. Surely that's simple at
least to verbalize:
$ cat in_file | expand_all_parameters > out_file
