 * These functions parse an integer from a buffer that does not need to be
 * NUL-terminated. They return true on success, or false if no integer is found
 * (in which case errno is set to EINVAL) or if the integer is out of the
 * allowable range (in which case errno is ERANGE).
 *
 * You must pass in a non-NULL value for "ep", which returns a pointer to the
 * next character in the buf (similar to strtol(), etc).
 *
 * These functions always parse in base 10 (and do not allow input like "0xff"
 * to switch to base 16). They do not allow unit suffixes like git_parse_int(),
 * above.
