* Check for illegal character '=' in environment variable names.Wolfgang Denk2006-10-28-0/+5
| | | | | | | | Make sure the string passed as variable name does not contain a '=' character. This not only prevents the common error or typing "setenv foo=bar" instead of "setenv foo bar", but (more importantly) also closes a backdoor which allowed to delete write-protected environment variables, for example by using "setenv ethaddr=".
