Fix sample code:

- Put single space around binary operator or after a comma.
- Lineup case label with switch().
- ANSIfy.
- Use \e to print \.
- Deref the pointer to get a value.

 .Sh NOTES
 Note that if you e.g. try to read information from e.g. a ethernet
 driver where the name of the card is included in the third argument
-(e.g. ioctl(s,READFROMETH,struct ifreq *)), then you have to use
+(e.g. ioctl(s, READFROMETH, struct ifreq *)), then you have to use
 the _IOWR() form not the _IOR(), as passing the name of the card to the
 kernel already consists of writing data.
