lineedit: support empty PATH entries in tab completion
Zero-length path prefixes can be specified in PATH as a leading or trailing colon or two adjacent colons. POSIX says that the use of zero-length prefixes to refer to the current directory is a legacy feature. Nonetheless the shells in BusyBox respect this feature, as does 'which'. Tab-completion of executables using PATH should support this too. function old new delta complete_cmd_dir_file 934 931 -3 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-3) Total: -3 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
