#9 unmatched brace/quote in list error

[Arunmozhi V]

This error occurs during command completions. For example, type the following to get the error

puts "<tab>

The problem is due to the wrong usage of catch, similar to the bug 754797.

Fix:
In the procedures Llength, Lindex and Lrange, change the following
if {[catch [list ...]]}
to
if {[catch {...}]}
