/* Mar 16, 2003 Manuel Novoa III (mjn3@codepoet.org)
|
||||
*
|
||||
* Because of behavioral differences, implemented configurable SUSv3
|
||||
* or 'fancy' gnu-ish behaviors. Also, reduced size and fixed bugs.
|
||||
* 1) In handling '\c' escape, the previous version only suppressed the
|
||||
* trailing newline. SUSv3 specifies _no_ output after '\c'.
|
||||
* 2) SUSv3 specifies that octal escapes are of the form \0{#{#{#}}}.
|
||||
* The previous version did not allow 4-digit octals.
