Prior change seemed not to be able to substitute for all
the actual %letter strings in a format string like e.g.:
Name: %10n \\ Sequence: %10c \\ Resource: %10a Done
leaving % format strings hanging. The correct thing
to do is to do all the format replacements and >then<
go back and escape any remaining %'s the user may have
pathalogically left in the format string. The
current version has been tested on a nasty format
string that looks like:
Name: %10n \\ Sequence: %10c \\ Resource: %10a Done % 10% done %10 %b done
and not only does not loop, but produces LaTeX output that can print.
