strange conditionals in bar-line.cc

[Marc Hohl]

Hello list,

while analyzing and rewriting Bar_line::compound_barline in scheme
I stumbled across an inconsistency:

In Bar_line::print, the function compound_barline is called only if
the length of bar-extent is > 0.

In Bar_line::compound_barline, there is

h = extent.length ();

and later

if (str == "|." || ( h == 0 && str == ":|"))

IIUC, h == 0 could never be true, isn't it?

Regards

Marc
