* //Where:// everywhere Creole markup is interpreted, i.e. everywhere except in
preformatted blocks and inline nowiki.
* //Effect://
** when the next character is a letter (a-z or A-Z) or a digit (0-9), the backslash is not considered as an escape character and both the backslash and the letter or digit are preserved in the output
** when the next character is a space, a tab or an end of line, both the backslash and the next character are consumed and a linebreak is generated
** in all other cases, the backslash is discarded and the following character is written verbatim to the output.
* //Rationale://
** rules are simple
** a single character is escaped, which corresponds to what authors want (they want to control characters in the output stream, not to preserve entire Creole markup sequences) and is robust with respect to other Wiki markup and future evolution
** the backslash can still be used in most Windows paths where it is usually followed by letters or digits
** the definition of letter and digits (7-bit ASCII or 7-bit UTF-8) is simple to implement and to understand
** backslash itself does not need a different escape mechanism
** linebreaks can move to the end or beginning of a line without problem
** white space at the end of lines, which is invisible, has no effect
** preformatted blocks and inline nowiki can still contain unescaped backslashes, which is important because backslashes are very common in many programming languages; their end tag (triple-right-brace) can already be escaped

* conflicts with some existing markup involving tilde (strike-out or emphasis)
* Several shells use ~ to stand for the user's home directory, and refer to files using ~/.emacs, for example.
