Subject: include/is: Rename is_digit() to is_digits()
X-Git-Url: https://git.corax.cc/?a=commitdiff_plain;h=c4e3cdf090344e2d81a339db05f70de3fd010546;p=toolbox

include/is: Rename is_digit() to is_digits()

The name of the is_digit() function was originally taken from the
Standard C library function of the same name. However, that function
checks only a single character, while this function compares all
characters in a string. To avoid confusion, this commit renames the
function to is_digits().
