If it would help I am close to a LaTeX tokeniser close to the one described in
the TeXbook (Knuth). I figured mathed need it and could send a copy to an
interested developer for bug flattening and use elsewhere. It could surely
squash problems with reading filenames wiht a few newliines and spaces in them
(yup, you are reading straight---linux et al allow anything except / and \0 in
filenames, so you could do shell code with the aid of a few directories).
Currently it does not handle delimited parameters, catcode magic,
\string, \csname<..blah..>\endcsname and macro expansion in general.
macro expansion or \csanme<blah>\endcsname and catcode magic. Macro expansion
is not supported yet either. Fixers are welcome to add the missing bits.
Finally here is a macro you might like, shamelessly adapted from an AMS macro
in the TeXbook. It gives you a box flush right, seperated by at least 4em from
the text, with a new line if need be. Note: this macro only works at the end of
a paragraph and works by adjusting the line break parameters.
\long\def\endpf{\ifvmode\hbox{}\fi\unskip\nobreak\penalty50\hskip4em\mbox{}\par
fillskip=0pt\hfill$\Box$}
