This includes escaping of characters special to the shell
as well as special to Perl, e.g., leading `<' or `>'.
For example, when $file starts with `>', `open ">$file"'
wrongly tries to append to a different file.

When constructing paths with IFS=:, quote the path. If we're
constructing a DOS-style absolute path, we don't want to split it

Adjust all uses.

variables, they are really part of the tokens.
Split the input line on spaces and then look for tokens.
Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
because of `lex$U.$(OBJEXT)'.
