libedit: Reduce surprising behaviour with filename completion some more:

2010-06-15T22:23:21Z

* Quote '*', '?' and '['. While it may be more useful to expand them to matching pathnames, this at least matches with the completion we do. * '@' is a regular character for filenames. Some other shells do @ completion but we do not. * Prefix names starting with '-' and '+' with './' so they are not seen as options.

libedit: Allow simple quoting in filename completion.

The completer recognizes characters escaped with backslashes as being literal parts of a word, and adds backslashes to avoid almost all misinterpretation. In particular, filenames containing spaces can be completed correctly. For bug compatibility with the NetBSD version, the improved completion function has a new name, _el_fn_sh_complete, and _el_fn_complete is unchanged. Submitted by: Guy Yur

libedit: Fix a bug that could make completion listings incomplete.

The element matches[0] is the common prefix and is not counted in len, so subtracting 1 is not needed. A counter for the number of matches per line was incremented twice. Submitted by: Guy Yur

libedit: Add basic filename completion code from NetBSD.

2010-06-13T17:04:42Z

This will be used to provide filename completion in sh(1). Changes from the NetBSD code: * wide character support disabled, as in the rest of libedit * config.h and related portability stuff reduced/disabled, as in the rest of libedit Submitted by: Guy Yur Obtained from: NetBSD
