v1.6.4

• Added rl_buffer:hassuggestion() and rl_buffer:insertsuggestion() for direct access to inserting suggestions without invoking Readline commands.
• Added clink.dirmatchesexact() and clink.filematchesexact() which are the same as the non-exact variants, except these don't append a * to the search pattern. For example, clink.filematchesexact("*.zip") can collect exactly "*.zip" file matches instead of "*.zip*".
• Added OS version info to clink info.
• Added UNC share name completion when using Executable Completion (the exec.enable setting).
• Fixed completing input . or .. when the exec.enable setting is enabled.
• Fixed applying colored-completion-prefix when match display filtering is active or a match has a custom display field.
• Fixed the exec.path setting so it doesn't accidentally include directories if their names end with an executable extension such as .exe.
• Fixed finding an argmatcher registered with a full path (e.g. c:\foo\bar.exe) when a full path is entered without a drive letter (e.g. enter \foo\bar.exe).
• Fixed #562; clink autorun install strips quotes by mistake.
