Fix issue in the lszdev command where column names if using the --pairs command line switch can contain characters that are not allowed to be used as variable names in a shell environment. Replace bad characters in column names by an underscore if the --shell command line switch is specified along with the --pairs switch. The additional --shell switch mimics what is already available in the lsblk command and thus it shall be used along with the --pairs switch. Signed-off-by: Daniel S.
