Summary:                    An extra space is added to traced statements in
--trace mode
Description: 
When running CMake with the "--trace" command line option, the traced statements
are echoed in the trace output file.

The problem is that most traced statements have an extra space added at the end
of the traced statements.  So, for example, "set(MSVC11 1)" is outputted in the
trace file as "set(MSVC11 1 )" (note the extra space before the closing
parenthesis).  This is true for every statement except for the "else()"
statement, which does not add the extra space.

The reason why this issue should be fixed is because on several occasions I have
copied the traced statement and attempted to search for the statement using a
text editor.  The search will always fail because of the added space.  In any
case, it is proper for the exact trace statement to be outputted, not a modified
version.

Steps to Reproduce: 
Run any CMake build, specifying the "--trace" option on the command line.

Additional Information: 
The only statement that does not add an undesired space is the "else()"
statement.
