Partial revert "htable: handle v. unlikely case where entries look deleted/empty."

[ccan] / README

The C Code Archive Network: http://ccodearchive.net

You can find a set of helper utilities under tools/ and the modules
under ccan/.  The recommended way to add ccan modules to your project
is to create a ccan/ directory and add one module per subdirectory
(see tools/create-ccan-tree).

Enjoy!
