The libedit versions of {readline,history}.h are in /usr/include/edit so as to not conflict with the GNU libreadline versions. To use the libedit readline(3) one should add "-I/usr/include/edit" to their Makefile (spelled "-I${DESTDIR}/${INCLUDEDIR}/edit" within the FreeBSD source tree). * Enable its use in the BSD licensed utilities that support readline(3). * histedit.h is moved into libedit's directory * Add basic filename completion code. * Allow simple quoting in filename completion.
