Ron Yorston 760b627e2a 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.
