Commit Message

fmt: validate width

* I observed a suspicious warning when providing negative number as input...
%perl fmt -w-1000000 a.c > /dev/null
Negative repeat count does nothing at fmt line 34.

* Value for -w must be an int; follow OpenBSD fmt and raise error for 0 and negative
* test1: "perl fmt -w 1.1  a.c" --> already covered by Getopt::Long
* test2: "perl fmt -w''  a.c" --> same as test1
* test3: "perl fmt -w0  a.c" --> new validation
* test4: "perl fmt -w-100  a.c" --> same as test3
