extensions#whitespace: fix false positive for check_mix_indent_file()

Browse Source 
This patch prevents check_mix_indent_file() form notifying a "mix-ident-file"
when working where C/CPP using space and comment like:
/**
 * Some comment on the 1st column that shall not trigger check_indent_file()
 */
This kind of file can be found in linux kernel for example.
