Provide a layer of indirection between the readline compatibility functions
and our internal implementation, so that we have the freedom to change the
function signature.
+ the rl_callback_handler_install takes a pointer to a void function
which has one char * argument (it's called that way in the readline
emulation source, otherwise there's no way to pass the line buffer
to the function which processes the line when EOL is encountered)
+ provide a prototype for that function signature and use it
Makes the callback readline interface work now.
SYMLINKS to install symlinked header files. INCSYMLINKS are installed with
'make includes'. This avoids using SYMLINKS and hacks with the 'linkinstall'
target in <bsd.links.mk>, as linksinstall occurs in 'make install' and hacks
to get it to occur in 'make includes' weren't robust, as seen in lib/libdes.
Yet more improvements to bsd.README.
Ensure that the <readline/history.h> link to <readline/readline.h> is
installed too for 'make includes'. Also, avoid creating obj dir.
This is finally real fix for lib/12929.
XXX Is this right?
them there.
readline.h of libedit had to move to subdirectory 'readline', due to the way
BSD makefiles work; this is better than potentially fragile Makefile hacks
