Enable or disable source code styling. This affects whether source
code, such as the output of the @code{list} command, is styled. Note
that source styling only works if styling in general is enabled, and
if @value{GDBN} was linked with the GNU Source Highlight library. The

code, such as the output of the @code{list} command, is styled. The
default is @samp{on}. Note that source styling only works if styling
in general is enabled, and if a source highlighting library is
available to @value{GDBN}.
There are two ways that highlighting can be done. First, if
@value{GDBN} was linked with the GNU Source Highlight library, then it
is used. Otherwise, if @value{GDBN} was configured with Python
scripting support, and if the Python Pygments package is available,
then it will be used.
