[PATCH] fold: Add '-c' (cut) option to cut off lines at a specific WIDTH

[jhx]

Hello everyone,

I personally often use 'fold' to break up some long lines, which works 
well. Lately I have been in the need to cut of a line at a specific 
length - removing the rest of the line. I made a small patch for 'fold' 
to do just that. The line gets cut off at WIDTH (specified via -w WIDTH) 
and three dots will be printed for a more appealing output. The new 
option added is '-c' for 'cut'.
I checked out the newest code via Git and compiled 'fold' with the patch 
attached to this mail. (No errors/warnings were output).

Attached you will find the patch for 'fold'.

Apologies if there is something missing/wrong - Never contributed to any 
GNU software before. :)

Greetings

Julian "jhx"
