You would want to avoid splitting within character strings
(print(";")) and in comments (print(2); ls() # This prints 2; then
lists...) The comment char could also appear in a character string,
where it does not mean the start of a comment...
Not sure how to accomplish that using strsplit (or in general using
just regular expressions).
