[PATCH] less.c: width/prec arguments to printf must be type int

[Rich Felker]

posix requires regoff_t to be able to hold the largest value that can
fit in either off_t or ssize_t. thus using regoff_t for a printf
format specifier's width or precision is wrong and will lead to
crashes on a compliant implementation with 32bit int and 64bit
size_t/off_t.
