+ LaTeX reader did not parse metadata correctly. Now the title,
author, and date are parsed correctly, and everything else in
the preamble is skipped.
+ Simplified parsing of LaTeX command arguments and options.
The function commandArgs now returns a list of arguments OR
options (in whatever order they appear). The brackets are
included, and a new stripFirstAndLast function is provided
to strip them off when needed. This fixes a problem in dealing
with \newcommand, etc.
+ Added a "try" before "parser" in definition of notFollowedBy'
combinator. Adjusted the code using this combinator accordingly.
+ Changed handling of code blocks. Previously, some readers allowed
trailing newlines, while others stripped them. Now, all readers
strip trailing newlines in code blocks; writers insert a newline
at the end of code blocks as needed.
+ Changed test suite to reflect these changes.
