[nasal-cvs] driver.nas io.nas regex.nas unix.nas

[Andy Ross]

Update of /home/nasal-cvs/nasal/lib
In directory purr:/tmp/cvs-serv31105/lib

Modified Files:
	driver.nas regex.nas unix.nas 
Added Files:
	io.nas 
Log Message:
Fix argument ordering issues in regex sub/sub_all functions.
Change naming of group variables in substitute expressions.

Add a soft-coded readfile() function to the io module.

Allow ghost destroy callbacks to be null (and ignored) instead of
causing a crash.

Include the readline library under the right HAVE_* symbol.

Add a workaround to what appears (?) to be a PCRE bug with the
startoffset parameter to pcre_exec.  Do the offset processing
outside the call.

Update the apache module to use the module system via driver.nas.
The gethdr() and getcgi() builtins now return a vector of all
keys when called with no arguments.  Update the sample code and
README to be a little more illustrative.  Change the ".nas"
convention for "servlet" files to ".ns" to avoid colliding with
regular nasal source files on the same server (i.e. sample.nas).
